WMS software - watershed modeling
The Watershed Modeling System or WMS software is a comprehensive graphical modeling environment for all phases of watershed hydrology and hydraulics. The WMS software includes powerful tools to automate modeling processes such as automated basin delineation, geometric parameter calculations, GIS overlay computations (CN, rainfall depth, roughness coefficients, etc.), cross-section extraction from terrain data, and many more! With the release of the WMS software version 8, hydrologic modeling with HEC-1 (HEC-HMS), TR-20, TR-55, Rational Method, NFF, MODRAT, and HSPF is now supported. Hydraulic models now supported in the WMS software include HEC-RAS and CE QUAL W2. 2D integrated hydrology (including channel hydraulics and groundwater interaction) can now be modeled with GSSHA. All of this in a GIS-based data processing framework will make the task of watershed modeling and mapping easier than ever before.
The WMS software's modular design enables the user to select modules in custom combinations, allowing the user to choose only those hydrologic modeling capabilities that are required. Additional WMS software modules can be purchased and added at any time. The WMS software will dynamically link to these subsequent modules at run time—automatically adding additional modeling capability to the software.

WinFlow overview

WinFlow is an interactive, analytical model that simulates two-dimensional steady-state and transient ground-water flow (both confined and unconfined aquifers) with wells, uniform recharge, circular recharge/discharge areas, and line sources or sinks. The model depicts the flow field using streamlines, particle traces, and water-level contours. WinFlow has the same basic capabilities as Geraghty & Miller's QuickFlow software, although many features are different or enhanced.

WinFlow simulates both steady-state and transient flow. The steady-state module simulates ground-water flow in a horizontal plane using analytical functions developed by Strack (1989). The transient module uses equations developed by Theis (1935) and by Hantush and Jacob (1955) for confined and leaky aquifers, respectively.

WinFlow is simple to use and highly interactive, allowing you to create an analytical model in minutes. The software features standard Windows pulldown menus and dialogs to facilitate the model design. Common menu selections and commands are also available on the toolbar. The entire WinFlow manual is available as on-line, context-sensitive help.

WinFlow produces report-quality graphics using any Windows device driver. Output may also be exported to a wide variety of file types, including SURFER, Geosoft, Spyglass, Windows Metafiles, and AutoCAD-compatible DXF files.

WinFlow features

Some of the key features include:

* Simulates both steady-state and transient flow in confined and unconfined aquifers
* Simulates effects of wells, linesinks, ponds, and recharge
* Imports map files in DXF format, QuickFlow format, or ModelCad format
* Simple data input
* Calibration targets and calculation of calibration statistics
* Double-click an element to edit
* Click and drag to reposition elements, streamlines, or particles
* Multiple models may be open at one time
* Cut, copy, and paste elements to/from the clipboard
* Maps may be printed using any Windows device driver
* Full context-sensitive help system (the entire manual is on-line)
* Drag-and-drop input files into the WinFlow window

WinTran
WinTran couples the steady-state groundwater flow model from WinFlow with a contaminant transport model. The transport model has the feel of an analytic model but is actually an embedded finite-element simulator. The finite-element transport model is constructed automatically by the software but displays numerical criteria (Peclet and Courant numbers) to allow the user to avoid numerical or mass balance problems.

WinTran- contaminant transport made easy

Contaminant mass may be injected or extracted using any of the analytic elements, including wells, ponds, and linesinks. In addition, constant concentration elements have been added. WinTran displays both head and concentration contours and concentration may be plotted versus time at selected monitoring locations. The transport model includes the effects of dispersion, linear sorption (retardation), and first-order decay. Other features include:

* Simulates steady-state flow and transient transport in confined & unconfined aquifers
* Simulates effects of wells, linesinks, ponds, and constant concentration sources
* 32-bit software uses all memory available to Windows; Supports Windows V3.1 (with Win32s), NT, 9X, ME, 2000 and XP
* Displays Peclet and Courant criteria during transport simulation
* Displays mass balance error during simulation
* Contours concentration at user-specified time steps during simulation
* Velocities computed either analytically or using finite-element flow model
* Maps may be printed using any Windows device driver
* WYSIWYG printing with print preview and user-defined margins
* Full context-sensitive help system (the entire manual is on-line)
* All other features are the same as WinFlow (except transient flow model)

Visual MODLOW 3D-Builder

2008-12-17T06:52:00.000-08:00

Visual MODFLOW 3D-Builder
Visual MODFLOW 3D-Builder provides you with advanced capabilities for building conceptual models completely independent of the numerical grid and within a unified modeling environment.
Visual MODFLOW 3D-Builder is the new generation in dynamic conceptual model building. Featuring a powerful multi-format object/data import tool and tested to work within the latest version of the Visual MODFLOW modeling environment, Visual MODFLOW 3D-Builder enables you to build impressive representations of your groundwater system within a single modeling environment. This means you save hours when building your numerical model.

# Build a conceptual model of the groundwater system, prior to the simulation - The geological formations, property model, and boundary conditions are all designed outside the numerical grid; this allows the flexibility to adjust your interpretation of the groundwater system before applying the numerical grid and converting to a numerical model.
# Build the model with minimal data pre-processing required - Working with grid-independent data allows you to maximize the use of your existing GIS data and incorporate physical geology and geographic conditions before designing the grid.
# Generate and Simulate regional and local-scaled models - As the only MODFLOW GUI that supports MODFLOW 2005-LGR, users are now able to design local grids around the area of interest, directly within the 2D/3D conceptual model environment. Calculated heads from a regional model can also be used as boundary conditions for local-scaled models.
# Design the correct model faster - The grid-independent raw data is left intact and is not constricted by grid cells when modifying the data or project objective. This allows you to generate multiple numerical models from the same conceptual model.
# Make changes to the model data and immediately see results - The conceptual model environment provides simultaneous 2D/3D views which translates to automatically seeing the results whenever changes to the data are made.

Data Import
Import raw data from numerous formats and edit data to suit your modeling requirements. Visual MODFLOW 3D-Builder allows you edit xyz points, shapefiles, or wells as well as map or draw attributes for points, polylines, and polygons. You can also view meta-data including statistics and history or edit settings for changing colors and styles for boundary conditions, wells, points, property zones, labels, and position.Flexible Data Operations

Conduct several arithmetic or geometric calculations and easily apply them to the geometry of your data objects or attributes.

Viewing and Editing
View your work simultaneously in 2D, 3D or spreadsheet style and automatically edit your information. Visual MODFLOW 3D-Builder’s interactive multi-view display allows you to make changes to your data and display the results in all viewer windows all at once.

Define, Import, and Adjust Surfaces

Define surfaces from well tops, cross sections from Hydro GeoAnalyst, or by interpolating xyz points. Import surfaces from USGS .DEM, Surfer GRD, ESRI Ascii GRD. Manually adjust surfaces in 2d/3d or by editing your xyz points. Visual MODFLOW 3D-Builder delivers key features for:

* Loading well tops and creating surface coverage to represent formations
* Loading fence diagrams, cross-sections from Hydro GeoAnalyst, and interpolating contact points to create surfaces

Structure and Area Layers
Define the conceptual model area from a polygon and vertical horizons from surfaces. Several horizon types accommodate various geological conditions including pinchouts and discontinuous layers.

Property Zones
Use Shapefiles or CAD polygons/polylines to define property zones. Visual MODFLOW 3D-Builder supports several methods for defining property zone values, including: constant values, surfaces (2D Grid), and 3D Gridded Data.

Boundary Conditions
Define boundary geometry and attributes with Shapefiles or CAD polygons/polylines or by using the supported LAK and FHB packages.

Support for Horizontal Wells

Define values for entire zones, or use linear gradient. Methods for defining property zone values include:

* Constant value
* Surface (2D Grid) (eg river stage from DEM)
* 3D Gridded Data (recharge/evt)
* time schedule
* Shapefile attributes

Numerical Grid

Define multiple vertical discretizations including deformed, uniformed and semi-uniform

* Deformed - easy to design, requires a smaller number of layers
* Uniform (Rectilinear grid) - requires larger number of cells, but fully respects the finite-difference assumptions
* Semi-Uniformed - Top and bottom layers deform to the horizons; in between, a set of uniformly thick layers will be generated.

Translation to MODFLOW

Once your simulation model domain is defined, you can easily translate the conceptual objects to the simulation model grid and create the necessary MODFLOW input files. Visual MODFLOW 3D-Builder allows you to:

* Define multiple grid discretizations
* Define up to 9 child grids inside a parent grid with the built-in Local Grid refinement tool
* Translate as MODFLOW parameters (for use in PES)
* Select MODFLOW packages to represent boundary conditions (eg, model a river using MODFLOW RIV package or CHD package)
* Import MODFLOW files into Visual MODFLOW for running the simulation

* Interpretation of dipmeter data using SCAT techniques
* Create Tadpole plots
* Commands accessible from menus or toolbar
* Imports ASCII format dipmeter log data
* Plot dip versus azimuth, tangent plots and longitudinal/transverse projections
* Fit data with theoretical fold curves

QuickDip is an easy to use program for the interpretation of dipmeter data using statistical curvature analysis techniques (SCAT). The main menu items are accessible from the QuickDip Toolbar. QuickDip supports import of dipmeter data from ASCII files and allows the user to save interpretation project files.

Dip and Azimuth versus Depth Plot
The dip and azimuth versus depth plot is useful for identifying dip domains as well as faults and folds. Depth intervals can be color coded by clicking on the color bar and dragging the color boundaries to the desired locations. Horizon labels can be added and displayed to aid interpretation. Specific depth intervals can be displayed using the zoom tool.

Dip versus Azimuth Plot
The dip versus azimuth plot allows the easy identification of fold forms. The "horseshoe" shaped theoretical fold curve can be visually fit to the data by simply clicking and dragging on the plot. The longitudinal direction and plunge of the fold can then be estimated. The histogram on the plot shows the total number of points in each bin.

Tangent Plot
The tangent plot is also useful for identifying folds. Cylindrical folds plot as a straight line on the tangent plot. The theoretical fold curve can be visually fit to the data by clicking and dragging on the plot.

Transverse and Longitudinal Dip versus Depth Plot
The transverse and longitudinal dip versus depth plot shows the dip components in the transverse and longitudinal directions. Crestal and troughal planes are indicated at depths where transverse dip crosses zero as shown in the example below at about 1155 feet (the depth where transverse dip changes direction).

Save and Retrieve Interpretations
The Save Interpretations command saves an all parameters associated with an interpretation including the name, depth interval, colors, and theoretical fold parameters. The Retrieve Interpretation command allows the interpretation to be retrieved by name. All plot parameters are restored for the retrieved interpretation.

Save Project
The Save Project command or toolbar button saves an interpretation project to a project file. The file includes all interpretations and parameters settings.

Zoom, Unzoom and Full Range
The Zoom tool allows the user to zoom on a depth interval on any depth plot. The Unzoom tool returns the display to previous zoom levels. The Full Range tool resets all displays to the full depth range of the log.

Horizons and Formation Tops
Up to 20 horizons may be labeled on depth plots. Horizons can be input from an ASCII file or entered and saved using the Horizons dialog.

Parameter Control
With QuickDip, the user has full control over most parameters including: symbol size, # of colors, colors, # of histogram bins, limit of tangent plot, show tadpoles, show theoretical curves, curve width, and show horizons.

GS+ Geostatistics Software

2008-12-15T01:59:00.000-08:00

GS+ Geostatistics Software
GS+ is a comprehensive geostatistics software program that is fast, efficient, and easy to use. GS+ provides all geostatistics components, from semivariance analysis through kriging and mapping, in a single integrated software program widely praised for its flexibility and friendly interface. Many users are surprised that geostatistical analysis can be so easy and intuitive.

What is geostatistics? Geostatistics is a class of statistical techniques developed to analyze and predict values of a variable distributed in space or time. It begins with a type of autocorrelation analysis called variography or semivariance analysis, in which the degree of self-similarity is displayed as a variogram. The variogram model is used to predict unsampled locations by kriging or conditional simulation, which produces estimates of the variable across the entire spatial or temporal domain.

GS+ software was first introduced in 1988. Geostatistics is not an add-on feature of GS+ - it is at the heart of the software. Many of our users have access to other geostatistics tools within their favorite GIS or mapping programs but come to GS+ for their serious geostatistical analyses, especially for exploring geostatistical relationships within data sets. Because GS+ output is compatible with industry standards, GS+ can be used directly with many of these other programs. Or it can be used standalone - GS+ has its own data worksheet (which also accepts MicroSoft® Excel®, Access®, and other types of data files) and produces its own maps for those users who are not working with other mapping programs.

GS+ is compatible with modern Windows platforms (see system requirements) and accepts data files with as many as 2 billion records. Algorithms are fast and dependable. Geostatistical analysis is computationally intensive - prior to 1988 most analyses had to be performed on supercomputers, but GS+ allows the Windows environment to handle most data sets with ease. Written in a combination of Visual Studio and Fortran, and drawing on GSLIB subroutines, GS+ shows that computation speed, flexibility, and an intuitive interface are compatible.

Numerous scientists, engineers, and students worldwide are using GS+.

Take a look at the GS+ overview for a quick tour of the software's main features, including pictures of all major windows. See featured statistics for a quick listing of the various statistics provided.

Workflows have been improved through simplification of the Workspace Tree and the addition of new controls to change the status of selection, edit and zoom for individual layers.

The main changes include:
* Selection and Edit controls have been added to enable interaction with feature databases and selectable objects.
* A Zoom function has been added allowing the user to zoom to the extents of a specific dataset of object in a single click.

Grid Surfaces

The grid controls have been enhanced to support a number of new data formats. In addition to this, a higher degree of control has been provided for color mapping and building custom visualization palettes.

Some of the new features include:
* New Color Mapping Control
User-defined color maps can now easily be defined via an interactive color mapping dialog. This provides simple or advanced options for applying custom color transforms to enhance the appearance of grid files and emphasize subtle variations that would ordinarily be hidden using standard transform techniques.

* Grid Flipper
Added continuous and strobe modes to animate multiple grid displays and reveal trends across multiple surfaces.

The automated grid flipping utility for frames per second/seconds per frame control has been replaced with two drop-down lists for the numerical values of the units and the units themselves (i.e. spf/fps).
* Support for the following grid formats has been introduced
- Arc ASCII grid files (.ASC) support added
- MINEX grid format (.XYZ) support added
- Surfer ASCII grid file (.GRD) support added
- JPEG 2000 image (.jp2) support added for Located Image Surfaces

Bar Chart Line Style Fill
A new bar chart rendering style has been introduced to the line series for curve profiles, vertical plot graphs and standard graphs. The bars can be rendered in a solid color based on the value of the first point and will extend to the next point. The bar is outlined with the default line color and style.

2D and 3D Vectors

Direct read support for a number of additional 3D vector formats has been added in this release. These improvements make it significantly easier to achieve seamless workflow transitions between Encom PA and other geoscience software applications.

Also available with the new functionality of vector files is:

* Improved property dialogs including new surface and transparency controls.
* Style overrides for line weight, style and color for all 3D vector formats
* Support for the following file formats
- GoCAD vector file (.PL, .VS)
- ESRI 3D shapefile (.SHP)
- Surpac DTM file (.DTM)
- Vulcan Triangulation file (.00T)
- 3D Studio file (.3DS)

* A new Make Fill Hollow override option for 2D vector file objects. The option can be accessed from the Override tab of the 2D vector file property pages. Turning on these options will not allow the appearance of vectors to be edited.
* When displayed in a 3D window, 2D vector files can be vertically offset by a DTM grid, constant value of vertically scaled.

Data Manager
A new window called the Data Manager has been introduced into PA for drag and drop, closing unused data links and property editing of database links. The Data Manager also assists in visualizing the use of active data files by showing how many windows a particular file is used in.

Bearing and Distance Tool
A bearing and distance line tool has been implemented into the Main toolbar, improving interpretation and analysis techniques. The tool supports the single distance, total distance and bearing azimuth for a single line and polyline information.

Data Conditioning

Any data field or individual band in an array can now be easily preconditioned to remove nulls, set limits or convert bad values to nulls. This feature is accessed from the Workspace Tree, by expanding the input channel selection then selecting an individual data band.

This tool is used with points, curves and drillholes.

Batch Printing to PDF
The Batch Printing Wizard now supports output to PDF file format when the PDF software application installed is pdfFactory. This allows profiles and map displays to be easily batch printed directly to .PDF format for a more superior hardcopy presentation.

Editable Spreadsheets
The station rate field values can now be edited via the database spreadsheet view. Only Geosoft and Intrepid database types can be modified. If data is modified via the spreadsheet then the Update Views button will become active in the spreadsheet view. Clicking the Update Views will then redraw the document with the new data values. An update of the views will also automatically happen when the user closes the spreadsheet view if they have modified some data.

ECW Creation
The Save As Located Image... pop-up menu for 2D map displays now supports output to the ECW file format. This utility supports coordinate projection image compression and advanced resolution capabilities.

Drillholes

The Drillhole group handling has been updated for optimized memory usage and rendering performance to handle the demands of working with large drillhole databases. These enhancements mean geoscientists can now easily visualize vast numbers of 3D drillholes in real-time and thereby gain a much better understanding of the geophysical and geological information contained within them.

Other improvements include:

* New data handling options to improve color and thickness modulation control. Invalid or unwanted data can be temporarily assigned a null value in order to exclude them from the display.
* When operating in the select/navigate mode, summary information about objects below the cursor is reported in the status bar for drillholes, images and features. This information provides rapid feedback to the user when interpreting geological features or interrogating anomalies.
* Simplified interface to improve workflow and usability.
* A number of additional drillhole desurvey methods have been added.

2D Kriging
The Kriging algorithm is now also available in the 2D Interactive Gridding utility. Kriging is a geostatistical gridding method combining powerful sample searching capabilities with a statistically rigorous estimation technique. Point or block estimations can be made using either ordinary or simple Kriging.

Breaklines in 2D Gridding
The breakline feature allows the easy introduction of interpretive data points into the gridding process, without modifying the original database. Users can then enhance terrain trends such as ridge lines and valleys that are not well sampled in the data. A fault trend can be added by placing two sub-parallel breaklines with different elevations in a data gap where you have inferred the fault location. This method can also be used to introduce manual padding of grids to enhance long wavelength results for reduction to pole and pseudo-gravity FFT transformations.

Voxel Models

The voxel model handling in PA has been enhanced to support a wider range of the file formats and new display options. These display enhancements make it easier to view subtle anomalies and improve visualization of targets in their 3D context.

* New Color Mapping Utility
Provides advanced options for applying color and data transforms to enhance subtle features and reveal potentially hidden information.

* New Transparency Modulation Option
The transparency of cells in a voxel model can be individually modulated by defining an opacity table and data transform. By applying the transparency modulation, important regions in a voxel model can be revealed whilst retaining the context of the surrounding model.

* Color Legend files can now be used as a reference for color modulation in discretized gridded voxels. Custom color tables can also be applied to threshold and isosurface displays, allowing lithological control of the voxel display.
* Gemcom block model format support has been added.

Improved View Mode

The 2D window supports new visualization options.

* New Full Screen mode allowing the 3D display window to fill the entire monitor screen, proving useful for presentations.
* New Anaglyph Stereo (red/blue) view option for 3D stereo visualization. This mode allows the 3D window to be switched into 3D stereo when viewed in combination with a pair of red/blue anaglyph glasses. When used in combination with feature digitizing, this mode can be very useful for structural interpretations and anomaly detection.

3D Cursor Plane

A number of enhancements have been made to the 3D cursor plane to support and complement the new feature drawing/editing capability.

These improvements include:

* New Clipping Options
The cursor plane property dialog now includes extra clipping controls, allowing the specification of either a clipping envelope or slice to be centered on the cursor plane.
* New Locking Options
The cursor plane can be locked temporarily along any orientation to constrain its position when drawing or editing features and slicing through the 3D view.

Transform Vector File Utility

In continuing Encom's commitment to improving data access and interoperability with PA, the original Transform DXF utility has been upgraded to support a range of additional 3D file formats and some new transformation options. Improvements include:

* Multi-Format Import and Export
A range of additional vector formats are now supported by the utility, including 3D Studio (.3DS), ESRI (.SHP, .ADF), MapInfo (.TAB, .MIF), Datamine (.DM), Gemcom (.BT2), GoCAD (.TS, .PL, .VS), Vulcan (.00t) and AutoCAD (.DXF).
* New Reprojection Option
Vector files can now be easily transformed and reprojected between standard coordinate systems.

3D Vector to Grid File Conversion Utility
A new plug-in has been introduced to convert a 3D Vector File (such as .DXF file) into a Grid Surface file. This is particularly useful when working with unconformity surfaces or sedimentary horizons such as coal seams where you want to convert these into a grid surface.

Supported File Format Converters

PA easily converts between different file formats. The list of conversion tools in PA is growing and the list below is to remind you of the flexibility.

* General ASCII Table to Geosoft GDB
* ASCII auto-format detect to Geosoft GDB
* Geosoft i3 format files to GDB
* ASEG GDF ASCII to geosoft GDB
* MapInfo TAB to Geosoft GDB
* Geosoft GDB to MapInfo TAB

Use the complete family of features available to create the ultimate interpretations that drive compelling exploration decisions.

You can access the flexible Feature Manager for creating, visualizing and editing an interpretation in sections, maps and 3D volumes. Also use the Feature Manager for logging anomalies or targets into a database or drawing complex interpretations in maps, sections and 3D volumes

3D Kriging
Kriging is a geostatistical gridding method which has proven popular across a variety of industries due to its flexibility and data driven approach to surface interpolation. The Kriging methods has been implemented as a new gridding option in the 3D Grid Toolkit utility for creating voxel models.

New Feature Manager
The original Feature Manager has been redesigned to improve usability and simplify feature digitizing. The Feature Manager dialog and Feature Type have been replaced by a better database management and Feature Set control. The Features menu includes more functionality and is complemented by additional controls from the newly introduced Data Manager window.

New functionality includes:
* New Create Feature Database wizard for opening a new database
* Import from Vector File wizard menu option
* Export to .GDB or ASCII (.CSV) format - both options have been added to the Features menu. This executes the Feature Exporter utility with the appropriate file extension already selected
* Information Sheet for easy visualization of active (highlighted) feature object data fields

3D Feature Digitizing
3D feature digitizing/editing functionality has been implemented, enabling point, polyline and polygon objects to be digitized directly in a 3D window. These objects are stored in the same feature database, allowing them to be attributed with descriptive information or interrogated/queried using the familiar SQL query language. These 3D features can be exported to a range of common 3D data formats.

3D Solid Generator
The 3D Solid Generator has been updated with a new interactive interface and vastly enhanced meshing algorithms. These improvements make it easy to generate triangulated 3D surfaces rapidly and thereby test different geological ideas.

* New Dynamic Interface
The join path and output mesh can be previewed dynamically within the utility interface
* Improved Meshing Algorithm
A vastly improved interpolation algorithm can automatically detect and handle disconnected or bifurcating, objects in the same plane or objects with no dominant axis. It can also highlight potential errors prior to generating a surface triangulation
* Automated meshing of Multiple Bodies
Multiple bodies within a single feature dataset can be automatically meshed in one pass by choosing a body attribute field which distinguishes the bodies as specified by the user
* Tie Lines option added
The ability to specify a Feature Set containing tie lines has been added to the 3D Solid Generator to improve interpolation between the feature objects.

Section to Map Utility
A new plug-in utility has been added to read an .EGB file containing image sections and then convert the coordinates of these sections from vertical to hoizontal orientation. This allows sections to easily be displayed in plan view, draped over a grid image or raster image window.

AquiferWin32 Version 3 - the ultimate in pumping test analysis

AquiferWin32 is the most sophisticated software system for analysis and display of aquifer test results. AquiferWin32 combines powerful data management capabilities with everything you would expect in a Windows program. AquiferWin32 has been chosen by the Environment Agency of England and Wales and has become the software choice for groundwater scientists and engineers requiring cost effective and versatile analysis tools.

AquiferWin32 major features
* Data can be entered conveniently using the import wizard, or you can enter data manually, by cutting and pasting from spreadsheets or by importing text files.

* Data can be entered using any set of units and AquiferWin32 provides the most flexible unit conversion calculator of any aquifer test program. You may define any set of units for any variable and change these units at any time!
* AquiferWin32 allows you to analyse your data using either manual on-screen curve matching, by the click-and-drag feature, or via automated statistical matching techniques.

Unlike some other pumping test analysis software, AquiferWin32 displays an unlimited number of type curves for multiple-type curve techniques (e.g. Neuman unconfined). You specify which type curves you want to view. This is also handy for creating custom type curve graphs for use in the field. These are some of the most important features in AquiferWin32. Please take a look at our free demo and see that AquiferWin32 is the best software for analysing aquifer test data!

Major features include:

* Simultaneous optimization of multiple data sets
* Serves as archive for raw data with options for data conversions during analysis
* Full control of parameter and data units on a well by well basis
* Global unit changes
* Parameter-based unit conversion calculator
* Dockable toolbars with tool tips
* WYSIWYG Printing with Print Preview
* Context-sensitive Help
* Multiple Document Interface
* Tab Views including spreadsheet, type curve, and map views
* Data spreadsheet in split window
* Liberal use of Property Sheets (Tab Dialogues) to maximise ease of use
* Native Windows 9X, NT, ME, 2000, XP
* Customizable Views - Text and Parameter Annotations, Legends, Symbols, Lines and Frames
* Frames support display of Bitmaps and Metafiles
* Site Map and Wells Displayed in Plan View
* Customizable Headers/Footers supporting Bitmaps and Metafiles
* Exports to DXF and Metafile formats
* Generates multi-curve type curve plots
* Full control of graphs - size, titles, axes, colours, fonts, dash patterns, line thickness etc

Features unique to AquiferWin32

AquiferWin32 does not require defining wells, simply import or enter the time/drawdown data into the spreadsheet, fill in the radial distance and pumping rate on a property sheet and either match the data manually or click the optimize button. It is that easy!

To manually match data to type curves, the user can simply depress the left mouse button, hold it down and drag the data. You do not even have to activate the procedure with a menu item as in some products. During this operation, all annotations, legends and the optional internal grid of the graph disappear to allow fewer distractions during the matching process. Go to full screen mode via the View/Full Screen menu and the internal part of the type curve graph is expanded to fill the entire screen to make manual matching even easier.

For multiple well analyses, no other pumping test analysis software provides a site plan to plot well locations over a basemap. Once defined, a multiple well analysis allows you to manually or automatically match each monitoring well individually by simply toggling among them. The appropriate data is constantly visible and editable in the split-window spreadsheet adjacent to the graph. You can select an individual data point by double-clicking the mouse within the graph and that point will be selected in the spreadsheet. You can also drag a rectangle around a range of data points on the graph to select them in the spreadsheet. (You would most likely do this to weight the points to give them less significance during optimizations.)

For multiple well analyses, you can optimize across all monitoring wells for whichever parameter or parameters you want. In a leaky-confined analyses, you might optimize Transmissivity and Storage Coefficient while leaving r/B free to vary among individual wells.

We are unaware of any other pumping test analysis software which has more options for analyzing and presenting your results. No other pumping test analysis software is more customizable with respect to legends, printed headers and footers, saving your defaults to the system registry, symbol control on each and every data point and generation of traditional type curve suites as seen in the literature (remember, if the axis labels are Time and Drawdown, it is not a type curve). AquiferWin32 supports variable pumping rates on all pumping test analyses involving type curves so you can analyze the drawdown and recovery data together or account for fluctuations in pumping rate during the test.

As far as we are aware, no other pumping test analysis software:

* Has a full implementation of derivative analysis in which you can generate suites of 1st order derivative type curves, do manual curve matches of 1st order derivative data to those type curves and perform an optimized match of the 1st order derivatives.
* Includes pumping test simulations with contour maps of drawdown and drawdown versus time graphs at any number of monitoring wells.
* Extends the analytical solutions into a full featured modeling environment with contour maps of hydraulic head or drawdown, color floods of head or drawdown and particle tracking. The modeling environment also optimizes calibration targets and is ideal for presentation of image well theory. How can you effectively demonstrate image well theory without a plan view contour map?

AquiferWin32 is user friendly
The term user-friendly is over used when talking about Windows software but it is important. You expect programs to operate a certain way so when you go from one application to another you know what to expect. AquiferWin32 adheres to more Windows standards that any other pumping test software even though it is not called "Aquiferwin32 for Windows". The win32 in the name is because AquiferWin32 was written specifically for 32-bit Windows platforms. It has never run in DOS or 16-bit Windows and caries with it no limitations from those operating systems.

Another aspect of user-friendly is cutting the learning curve when it comes to using new software. That is why we are combining slug test analysis, pumping test analysis, step test analysis, pumping test simulations and analytical flow modeling into one application with a common user-interface. Why learn a number of different applications when one will do?

Maybe the most important aspect of user-friendly is removing confusion. AquiferWin32 is designed to differentiate among distinct analysis types (slug tests, pumping tests etc) by storing them in different documents. In this way you won't encounter parameters or operations that have no meaning to the type of analysis you are doing.

Studio 3 Block Modelling Introduction

Block modeling is a very powerful technique which models deposits as a set of 3-D cells and sub-cells. Sub-cells are a unique Datamine concept, in which and cell may be split into any number of differently sized sub-cells to define any required level of local detail.

Models may represent geological structure, or grade distribution, or both. There is a choice of interpolation methods, statistical and geostatistical, and the model can be edited and examined interactively in plan or section.

Evaluations of reserves for the whole model or selected areas can be produced, and many different types of data can be processed at once.

Separate models representing different properties or zones can be combined and superimposed, and the models so created are used throughout the Datamine system. The cell/sub-cell structure is equally suitable for massive, layered, vein type or alluvial deposits.
Studio 3 block modelling
Reproduced with the Kind Permision of Ernest Henry Copper-Gold Mine

Cell models may be displayed over a wireframe surface, allowing for example the ore in the walls of a drive or an open pit to be shown, with user specified colours defined by filters.

Within a perimeter, cells may also be displayed at distances above or below the view plane, allowing for example selective examination of the model on the bench above or below the current plane without changing the view.

An evaluation method is also provided, in which a temporary wireframe model is constructed between any two user-defined three-dimensional perimeters and evaluated against the cell model

Studio 3 Block Modelling - Basic Principles

Geological Models

The purpose of a geological model is to accurately represent not just the grades of a deposit, but also its boundaries and internal structures. A Studio 3 geological model is composed of 3D 'rectangular' blocks, or cells, each of which has attributes such as grades, rocktypes, oxidization codes, etc.

Why use blocks?

Though many cell shapes, such as polygons, distorted cubes, mathematical surfaces and triangulations are possible none is completely general in application. The simplest form of three dimensional model consists of a rectangular grid in which each cell has the same dimensions. This is also the most commonly used type of model because it lends itself well to efficient handling in a computer. For some particular deposits there can be elegant solutions to the problem of representing grades and geological boundaries. A comprehensive modeling system such as Studio 3, however, requires a method that is applicable without modification to the widest possible range of deposits. The solution is to use a block model that allows rectangular cells of different dimensions.

Studio 3 Block Modelling - Defining the Model

Before creating a model you must define the region it will represent and the size of the parent cells it will contain. You store this information in a model prototype file, which contains the following components:

Model Fields - DATAMINE requires the following numeric fields in every model and prototype file. Note that instead of east, north and elevation, Studio 3 uses the generic names 'X', 'Y‘ and 'Z'. This is because you can align models to a local grid instead of the true coordinate grid.

XMORIG, YMORIG, ZMORIG - XYZ origin of the model. Studio 3 sets the origin with respect to the corner of the first parent cell (and not its centroid).

XINC, YINC, ZINC - XYZ cell dimensions. If the model is not to contain any subcells then these three fields can be implicit (not stored on every record). This will reduce the storage space required by the model.

NX, NY, NZ - Number of model parent cells in XYZ. Studio 3 allows a value of one for modeling seams. The number of cells, in combination with the cell dimensions, defines the extent of the model.

XC, YC, ZC - XYZ cell center coordinates.

IJK - Code generated and used by Studio 3 to uniquely identify each parent cell position within the model. Subcells that lie within the same parent cell will have the same IJK value.

Attributes - In addition the model can contain any extra attribute fields necessary

Studio 3 Block Modelling - Cells

Cell Size

A Parent cell is the largest cell allowed in a model. You set the size of these cells based on several factors such as the geostatistical properties, drillhole spacing, mining constraints, geology, topography.

Where your model needs greater definition, such as within thin seams or at the edges of boundaries, you can subdivide the parent cells into smaller subcells. You control the degree of parent cell splitting, and thus the size of the subcells.

A significant advantage of Studio 3 block modelling is that it is not necessary to create a cell in every position within the model. Only regions of interest, such as a mineralized zone, need be modelled. This can dramatically reduce both the computer power and disk storage you require.

Studio 3 Block Modelling - Parent Cell Splitting

Filling plane

Cell splitting can be done along any axis in the model. When you use a constraining boundary, such as a perimeter or wireframe, you also need to define a filling plane to control the direction of the cell splitting.

For example, if you set the filling plane to 'XY' then the process will create the specified number of subcells in both the X and Y directions. In the third axis the cell size will be calculated using seam filling. With seam filling the cell dimension is set automatically so that it precisely fits the perimeter or wireframe boundary. Thus, careful selection of the filling plane is important in providing the best possible modeling of geological boundaries.

Studio 3 Block Modelling - Rotated Block Models

A Rotated Model is one whose axes, and therefore cells, are rotated with respect to the coordinate system. It is particularly useful in the situation where you have a stratified orebody which is dipping and/or plunging. As you can see from the diagram Below the model cells provide a much better fit when the model Is rotated. Using a rotated model aligned to one or more of the major axes used to model the structure or shape of a deposit has the following advantages;

* a smaller number of subcells can be used
* the subcells provide a better fit to the boundary
* in particular circumstances there can be a small improvement in the grade evaluation.

Studio 3 Block Modelling - Combining Models

The ability to combine models is a powerful tool of Studio 3 geological modeling.

As well as allowing you to create complex models in simple stages, it also lets you later update and build upon your existing models. Understanding how Studio 3 combines models is therefore important.

For adding models the best option is to use the first model as a prototype for restructuring the second model.

Attribute fields

Any attribute fields such as lithology or grades are handled according to the following rules:

* If the fields are unique to each input model then all these fields are written to the output model. Those fields that do not get a value from either of the input models are set to undefined (-).
* If the same fields exist in both input models the 2nd model overwrites the common fields in the 1st model.

Combining cells

When models are added, the cells are first compared to find how they overlap.

* If cells do not overlap, or overlap exactly, then no cell splitting is done and only the cell attributes are updated.
* If the cells partially overlap then they are split along each cell boundary before updating the attribute fields. As the resulting cells must be rectangular the splitting will continue throughout the full length of a cell.

Studio 3 Geostatistics - Cross Validation
Cross Validation - XVALID

The cross-validation process XVALID is designed to assist in the selection of parameters for grade estimation, using the cross-validation method. The input data file is the sample data which will later be used for estimating grades into a block model. For kriging it allows different model variograms to be tested and compared. For inverse power of distance it allows different powers to be compared. The input to XVALID is consistent with the input required for the grade estimation process ESTIMA. In fact the three input parameter files are identical for the two processes. The cross-validation method works by removing each point in turn from the data file and estimating its value from the remaining data. In this way a table of actual and estimated values is created. A detailed statistical analysis is then carried out comparing the actuals and estimates. One or more of the estimation parameters can then be changed and the process rerun to see whether the new parameters improve the results of the statistical analysis. The method is therefore iterative, requiring several runs to establish the best set of parameters.

Cross Validation Optimization

Cross-validation is an iterative process – you make your first estimate, look at the stats, change one of the parameters, and try again to see if you improve the stats. XVOPT does all this for you. You need to define an initial or base set of parameters as before, but you also specify a minimum and maximum for each parameter. Then you define a step size for discrete increments between the maximum and minimum. XVOPT then just loops round for all possible combination of parameters and calculates the statistics. So what you also need to do is to define a sort of objective function. You specify weights for each statistic defining their relative importance, and penalty for the distance of the actual statistic from it’s target value. defining their relative importance, and a penalty for the distance of the actual statistic from its target value. The process then calculates the penalty for each run, weights them and finds the one with the lowest penalty points.

The following image displays the VARFIT process in action:

Studio 3 Geostatistics - Other Options (1)
SMUMOD The SMUMOD process uses the 'Lognormal Shortcut' method to estimate the recovered tonnage and recovered grade above a single user defined cut-off for a specified size of Selective Mining Unit (smu). The input file must be a standard model file containing a kriged grade estimate and a kriged variance. The output model file contains all the fields from the input file plus two additional fields: •the proportion of the block above the cut-off; •the grade of the proportion above cut-off. A Selective Mining Unit (SMU) is the smallest block size that can be mined selectively. The Dimension of an SMU are defined by parameter.

SMUHIS
The SMUHIS process creates a histogram file by evaluating a kriged model using the 'Lognormal Shortcut' method and estimating the tonnage distribution over the range of cutoffs specified for the histogram intervals for a specified size of Selective Mining Unit (smu). The data in this file can then be used to create grade/tonnage plots.

FFUNC
FUNC estimates the geostatistical F function. That is the variance of a point in a block based on a variogram model which is selected from the input variogram model file. The block whose F value is to be calculated is simulated by a 3 dimensional matrix of discretisation points. The F value is calculated as the average value of the variogram between each possible pair of discretisation

Studio 3 Geostatistics - Other Options (2)
Multiple Indicator Kriging (MIK)
The only transform used in Multiple Indicator Kriging (MIK) is the transform from a grade to a 0 or 1. The Affine Correction Method is used to take the output file from ESTIMA and correct the grades for SMU size. Details of the Affine Correction Method are given in Applied Geostatistics by Isaaks and Srivastarva pages 471-472.

Declustering Sample Data - DECLUST
Options:
Random Sample
Psuedo Random Sample
Sample Nearest Grid Center
Mean of Samples in Grid

Grade Estimation for Irregular Panels - PANELEST
The PANELEST command estimates the grade and variance of 2D or 3D panels. Panels are defined either as a set of strings, or as a set of 2D or 3D discretisation points. The interpolation methods available are nearest neighbour, inverse power of distance or kriging. In particular the process allows you to estimate a grade and a kriged variance for...
any perimeter, without the need to create a block model.
a subset of cells from a block model.

Mining technology

Datamine and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) have entered into an agreement, making Datamine a reseller of Sirovision.

Sirovision is a new technology that combines the power of digital photography with advanced mathematics to create value for the Mining industry. Sirovision produces rapid, accurate 3D structural models of mine features using affordable digital cameras.

Sirovision is more than a Spatial Data System; it is a Rock Mass Structure Mapping and Analysis System

Sirovision has been designed to support rapid mapping of mine features with a minimum of expertise in Photogrammetry. Using Sirovision, you can build accurate three-dimensional models from sections as small as 2 square meters up to 40,000 square meters in minutes. Using this system you can also create multiple 3D images in order to build an extended panoramic image.

What is Photogrammetry ?

Photogrammetry has been defined as
"The art, science and technology of obtaining reliable quantitative information about physical objects and the environment throughout the process of recording measuring and interpreting photographic images and patterns of radiant energy derived from sensor systems."

(Slama 1980 - Manual of Photography)

By taking two digital photographs of the same rock face, from different angles, combined with minimal survey data, a detailed 3D image is generated that is positioned accurately within the local coordinate system of a mine. Sirovision generates data at thousands of 3D points per second. The system provides facilities for accurate mapping and analysis such as characterisation of discontinuity orientation patterns and measurement of discontinuity spacing and persistence for use in many areas of mining and civil engineeering.

Sirovision can be used in:

* Blast Design
* Mine Design
* Slope Stability Analysis

Structural information is extracted using sophisticated mathematical techniques. The structure and lithology data is added to the geological model, while geotechnical features such as joint frequency, orientation and spacing are incorporated into the geotechnical model. Using these models geologists and engineers can provide informed instructions to production crews about ore/waste delineation, make better decisions about safety, enable the latest geology and geotechnical data to be used in mine design

The end result of this collaborative system is higher productivity and improved head grades.

* The 3D Imaging system quickly produces accurate, detailed three-dimensional images of mine features such as benches, pit walls and highwalls using affordable digital cameras.
* Creating 3D images takes minutes. Processing is done on standard PCs and requires no specialist expertise.
* Geologists, Civil Engineers and Mining Engineers can use the 3D data to obtain structural data covering any selected segment of the rock mass.
* The analysis system uses the three-dimensional images of a surface to provide a powerful tool for geologists and geotechnical engineers. The characteristics of joint sets can be determined quickly and accurately. The system provides a permanent digital record.

Sirovision lowers the time and cost barriers to building detailed geological and geotechnical models and maps based on data collection that is safe, cheap, fast and unbiased. Models that would normally be expensive, slow and labour-intensive to create can now be prepared in minutes.

Benefits

Sirovision can offer you significant benefits:
Geological Mapping * Rapid Accurate, localisation of geological features.
* High resolution 3D images supporting highly accurate mapping (unlike, for example, 3D point clouds or wireframes).
* Reliable traceability and quality control of digital records

Geotechnical Mapping * Superior data resolution: using commercially available cameras, a single pixel can represent 3mm up to 6mm depending on the hardware used, and distance from the photographed object.
* Orientation measurements are much more accurate when compared to other survey techniques.
* Independently validated data, resulting in a decreased bias in data.
* Measurements are not limited to scan lines or areas than can be physically accessed.
* Analysis techniques have been developed that are statistically more reliable that existing methods.
* Improved safety; personnel do not have to physically access the face being mapped.
* Improved productivity; up to 5 x faster to acquire and analyse structural data when compared to other surveying methods.

Analysis of Lithology and Mineralogy * High-definition 3D image provides an ideal perspective from which to achieve accurate visual interpretation of Lithology.
* Sirovision uses Visual Segmentation Techniques to provide an information-rich guide to the underlying mineralogy.
* Sirovision also gives an indication of the surface area of the banding against the surface area of the 3D image.
* Structural Analysis Planes and traces can be analysed in situ, giving immediate indication of Dip, Dip Direction and in the case of planes, surface volumes. * Structural Analysis of Dip & Dip Direction can be displayed using Datamine's Sirovision Visualisation Tools overlaid on to the actual 3D image - the level of information that can be derived from these presentations is astounding.

Analysis of Structure and Geotechical Analysis * Dip and dip direction displays.
* In Situ Structure Visualisation.
* Understand failure modes.
* Perform Kinematic Analysis.

Coming Soon...

Sirovision Underground - a turnkey solution for safer and more cost-effective mapping and analysis of geology, rock structure and surface topography of underground mine workings.

Studio 3 and Folded Orebody Data

Folded orebodies present their own unique complications when it comes to statistics (both classical & geostatistics) and grade estimation.

Traditional analysis uses straight line distances calculated from the East, North and Elevation coordinates of the data. In folded structures this is often wrong since you should use the true geological distances "down dip", "along strike" and "across strike".

UNFOLD lets you do this. Rather than picking an incorrect solution why not Unfold the orebody and get the correct answer? Unfold gives you the ability to model the mineralization in your stratabound deposits more accurately. By transforming your data into an Unfolded Coordinate System, Unfold allows you to produce statistics which provide better understanding of the mineralization Features:

* Accurate grade estimates.
* Better variograms which are easier to model.
* Calculate true stratigraphic distances between points.
* Process multiple seams simultaneously.
* Use Datamine's extensive statistics tools to evaluate your unfolded data.
* Use Datamine's powerful grade estimation tools to model grades in a true Unfolded Coordinate System.

Dynamic Anisotropy

2008-12-13T08:04:00.000-08:00

Mining technology

Improve your Grade Estimation with Dynamic Anisotropy
The Dynamic Anisotropy option has been added to Studio 3 which allows the anisotropy rotation angles for defining the search volume and variogram models to be defined individually for each cell in the model.Thus the search volume is oriented precisely and follows the trend of the mineralization, which leads to improved grade estimates.
The method is particularly suitable for gently folded and rolling orebodies where previously an average direction of mineralization would have been used.This is illustrated in the figure below which shows how the search ellipses follow the mineralization:

Not only does the search ellipse follow the mineralization but the same anisotropy angles are used for calculating the sample weights for inverse power of distance and for the rotation of the variogram model for kriging. The upper cross section in the figure below shows the grade profile using a horizontal search ellipse and the lower cross section using dynamic anisotropy.The improvement is obvious!

In can be shown that a misalignment of the search volume by just a few degrees can cause the interpolation of ore into waste and waste into ore leading to incorrect estimates. It is therefore very important to get the orientation of the search volume correctly aligned.In the case of highly folded or deformed orebodies Studio’s Unfold option still provides the optimal solution, but for more gently folded cases the Dynamic Anisotropy method provides a fast and easy to use option.

Wireframe Modelling

2008-12-13T02:52:00.000-08:00

Mining technology

* Studio 3 Wireframe Modelling Introduction
Studio 3 provides a fully comprehensive and interactive three dimensional system for creating, modifying, merging, intersecting, displaying and evaluating both solid models and Digital Terrain Models (DTMs).

Strings may be linked using 'point and click' selection methods and a choice of linking algorithms is included. The optimized method frequently allows even highly complex strings to be linked automatically without point tagging; however, tagging is also provided for greater control over linking.

Endlink, unlink, slice and evaluation (both volumetric and against a cell model) are also supplied. DTMs may be constructed from a set of points and strings, and linking constrained to lie within user-defined limits.

Studio 3 has the facility to turn wireframe models into cell and sub-cell models in a single pass with the amount of cell sub-division under user control. This unifies the concepts of wireframe and cell models, allowing varying grades within seams and orebodies to be represented in as much detail as required.

Studio 3 has updated algorithms for wireframe boolean operations:

* Union
* Merge
* Difference
* Intersection
* Split
* Extract
* Decimate etc.

Operations work on objects and create new objects as a result of the operation. Selection methods are based on attributes and/or filter expressions.

* Modeling Using Perimeters
A geological interpretation consists of section or plan drawings showing structure and mineral boundaries. These can be created directly within Datamine Studio using drillhole information and interactive graphics or by hand over hardcopy plots which you can later digitize.

As you digitize strings you should assign them codes or attributes to distinguish the different zones and rocktypes. Datamine can later assign these attributes to the cells created in the block model. Examples of attribute fields include Color, ZONE or Rocktype, or any other item you find necessary to describe the geology.

Using interactive graphics, perimeter points can be placed at the precise three-dimensional coordinates of selected drillhole intervals. DATAMINE calls this automatic positioning of points on existing screen objects snapping. For Datamine to fill the strings with cells they must form closed areas or perimeters. Ensure that adjacent boundaries abut up against each other with no gaps or overlaps. You can use interactive string utilities to automatically generate outlines from open overlapping strings. In this way common boundaries need to be digitized only once.

* Filling Perimeters
Perimeter filling requires that the perimeters be planar and lie in the 'XY', 'XZ' or 'YZ' plane. If the perimeters do not meet any of these conditions, you Will need to use wireframe modeling.

The process creates cells within the perimeter, perpendicular to the perimeters at a user defined projection distance either side of the perimeter. Typically this projection distance is set to half the section spacing and care needs to be taken to ensure that the values you use do not create gaps or overlapping cells between the sections.

The results will also be better if you closely space your sections and the geological structure lies

approximately along an orthogonal axis. Otherwise the model created may appear 'blocky' and a poor fit to the actual geology.

* Wireframe Modeling Modeling Using Wireframes
The most precise way to define a geological boundary in three-dimensions is with a wireframed surface or wireframed solid. Both are essentially the same except that wireframe solids enclose a volume while a wireframe surface is normally open. They may also differ in the techniques employed to create them. The use of wireframes, while giving more precision than perimeters, will require a thorough knowledge of how the deposit behaves in three-dimensions. The starting point for solid wireframe modeling is usually a series of perimeters outlining the geology. These perimeters need not be planar and may lie at any orientation. They must not however overlap in three dimensions with themselves (forming a knot or 'twisted bowtie' shape) or with adjacent perimeters.

Wireframe Concepts

Wireframes are defined on the basis of :

* GROUP: a GROUP can consist of one or more distinct wireframes which have either the same surface identifier, or different surface identifier.
* SURFACE: an individual wireframe SURFACE can be selected from within aGROUP of wireframes. This surface can be either a DTM or a solid wireframe.
* LINK: each wireframe surface consists of a number of individual links.

This classification of wireframe GROUP and SURFACE provides a means by which wireframes can be identified for operations such as combining and verifying wireframes which will be outlined later. It also provides greater control when using the ‘erase’ commands. You can erase GROUPs, SURFACEs, LINKs and individual triangles. The wireframe group, surface and link identifiers are stored in the wireframe point and triangle files as field GROUP, SURFACE and LINK respectively. These values are assigned internally by the system. It is possible to select wireframe data based on group and/or surface number.

* String Linking
String linking is a technique used to “link” closed perimeters together to form a solid volume. There are three linking algorithms used in Datamine which can be used depending on the nature and complexity of the perimeters.

* MINIMUM AREA - The system will create the triangulation which has the smallest wireframe surface area.
* EQUAL ANGLES - The system will create equi-angular triangles (i.e. equilateral or isosceles triangles).
* PROPORTIONAL LENGTH - This option will create triangles which best maintain their proportional position along the string. The starting edge for triangulation is determined either by user defined tag strings or, if selected by the system, the closest pair of points on the two strings. This option works best where the shape of the two strings is similar.

Wireframe advantages

Besides allowing you to build more precise models wireframes 0ffer other advantages over perimeters.These advantages include:

* You can slice wireframes and plot the slices in any plane.
* Your wireframe slices can also be converted to strings. This allows you to do your interpretation in one plane, wireframe the results and then create a new set of perimeters in a new orientation.
* You can very quickly calculate accurate volumes.
* They offer the clearest and most graphic way to display your designs to other people.

* Terrain Modelling
A Digital Terrain Model (DTM) is used to model surfaces representing topography or geological structures such as seams or faults.

You can create a DTM from contour strings or point data, or both combined.

See the images on the right for examples of DTM creation in Studio 3.

* Combining and Splitting Wireframes - Boolean Operations
The following Studio 3 commands represent some of the available commands that can be used to manipulate wireframe models:

* Merge/Split - This command will split two wireframes where they intersect and can be used for both open and closed wireframes.
* Solid-Union - The SOLID-UNION command allows you to combine wireframes
* Solid-Difference - The SOLID-DIFFERENCE command allows you to intersect two overlapping wireframes and update the first wireframe selected minus the overlap from the second wireframe selected.
* Solid-Intersection - The SOLID-INTERSECTION command can be used to find the common volume of two overlapping wireframes. The resultant wireframe represents the overlap of the two selected wireframes.
* Solid - Split at Plane - The SPLIT AT PLANE command can be used to split a wireframe along the intersection of the selected wireframe(s) with the current view plane.
* Solid - Multiple Split - The MULTIPLE SPLIT command is used to split a wireframe at regular intervals parallel to the viewplane. You must defined the interval used for splitting.
* DTM – Update - The DTM-UPDATE command is used to update one surface wireframe with another. The new surface is generated using the second wireframe selected to update the surface elevation.

Studio 3 is a new version of Datamine’s flagship geological modeling and mine planning product. Studio 3 provides multiple views on a wide range of data providing the most suitable environment in which to perform tasks within the mine planning cycle. The possible views and the type of data handled allow strategic and operational mine designs to be more easily communicated.

Studio 3 deals with its data in the form of objects. Unlike Studio Version 2, when a file is opened in Studio 3, such as a string file, the data in that file remains separate to the other loaded data and can be formatted, filtered and selected independently of other loaded data.This is identical to how data is treated in Downhole Explorer. Data objects can be merged and split on attribute fields or by using a filter expression to either combine or create new objects.

Geological and Geotechnical Mapping Using 3D Imaging

Datamine - For When Mining gets Serious.

The Datamine Group is the world's leading supplier of technology to the mining industry. Our goal is to become a key business partner for mining companies and consultancies by offering the best products and the best people in every major mining region in the world.

Datamine offices around the world are now shipping Studio 3, the latest version of Datamine's market leading Resource and Reserve Management System. With the release of Studio 3 we are now the first mining technology vendor offering integrated Virtual Reality!

Virtual Reality allows you to go beyond geological modeling and mine design! Now engineers can create a design and check how it will look to the production personnel who work it. You can place fixed and mobile plant into the mine environment to ensure the design is workable. Trucks and LHDs can be driven from the "operator's view" along proposed haul routes to check intersections and ramps in open pit and crosscut and tramming routes underground. "Float" outside the vehicle to check clearance dimensions for spotting and turning.

Studio 3 with InTouch Virtual Reality is available right now to new customers and as a "maintenance upgrade" to existing customers. Studio 3 is completely compatible with Studio 2.

Datamine is setting a new standard by becoming the first mining technology company to integrate a full virtual reality system into its core resource / reserves management system.

Imagine what can be achieved when you visualise geology, phased mine plans, safety considerations and mine-site rehabilitation schemes across multiple projects in a virtual world - well, starting with Studio 3, Datamine’s InTouch Virtual Reality technology comes standard with Studio Core.

You can place fixed plant and mobile equipment anywhere in the mine and check mine designs for clearances and safety margins. You can sit in the cab and operate the equipment from an operator’s point of view and see what he or she will see on the job. Drive a truck along the haul road you have designed and check the corners and intersections for visibility.

InTouchGPS can take live telemetry feed from mobile equipment in the pit to show the real time position of the equipment as well as status, task and load.

Applications of InTouch:

* Collaborative Immersive Resource Development - Geology and Mine Design

* Safety Reviews of mine designs – open pit and underground.

* GPS feed for real-time visualization or “shift replay” for productivity reviews.

* Executive Presentations for use at AGMs, public meetings and executive seminars.

* Mine Monitoring and Control mimic panel of the entire operation.

The desktop data immersion allows users to interrogate geochemistry, topography, structure, and geotech data and relate it to geology, mine planning, grade control, haulage, stockpiles, plant and fixed mining assets.

Exploration and mining staff will be able to visualise multiple forms of data in an easy-to-use 3D environment. The reality experience of immersion aids the recognition of trends and reduces the risk of data errors and minimising mine design problems.

A virtual world model of an operating pit can be built by draping aerial photos on the terrain model, linking objects to external datasets like blast models, stockpiles, telemetry, assays, maps, sections, schedules and any photorealistic objects that emulate reality. Even moving objects like trucks can operate on real world routes.

Use this to make realistic mine presentations for the public, shareholders, auditors, banks, regulatory agencies, and investors.

InTouch provides a new intuitive way to look at your geological and mining information. It uses Virtual Reality modeling with connections to external data sources to provide a realistic and simple visual method of examining and navigating through all your data. Uses include:

* Geological data immersion - unlock the full value of your geological data with full stereovision immersion right there on your desktop. Display fault planes, geophysical grids, geological interpretations, structural surface models, grade surface models, drillholes and terrain surfaces, then color and texture the objects to reveal their hidden secrets.
* Real world data connection - every object in the virtual world can be linked to other documents and programs accessible on the local network, company intranet or worldwide internet. You can click on say a drillhole to display a drill log or section plot, or on a blast markup line to report the tonnes and grades, or step inside the mine office and click on the telephone to dial-up and upload the latest drilling results - the possibilities are endless and limited only by your imagination.
* Terrain navigation - jump into any vehicle and take it for a drive up the road, across country, or down the mine. Take a visitor or a company director on a virtual tour of your exploration project or minesite. Change the transparency of the terrain surface and peer down to see the orebody and pit design surface.
* Fly-thru's - drape an aerial photo over your terrain surface and fly around your mine. Swing down into the pit then dive below ground and fly right inside the orebody.
* Simulations - define haulage routes, then add trucks, shovels, draglines, drill rigs and service vehicles and watch the mine come to life.

Conventional 3D visualization programs do little more than spin the data around while you view it, whereas InTouch is a 3D immersion system which puts you right inside your data. The data links then give you access to as much detail about the objects as you want, or wish to publish, and enable easy access to plots, logs, reports and charts without specialist knowledge of where the data is stored, the format it is stored in or the programs used to create them - in other words, it puts everyone in touch with the project. And because none of the objects, or the linked information are stored inside the document, any changes to the data are automatically reflected in the world view.

Data Imaging, Drill section and 3D visualisation software

INTERDEX is one of the world's most popular exploration software packages.
Exploration, Mining and Industrial minerals companies use the software routinely to visualise and interpret geoscientific data. Examples range from regional stratigraphic investigations to the preparation of cross sections, resource estimates, and the creation of images and contours of geochemical and topographical data. Sophisticated 3D displays can be created from images, drilling data, point data, and interpreted or surveyed lines and outlines.

This interactive program enables a geologist with average computer skills to quickly visualise patterns in data, and make daily, value adding decisions about a project.

Data collation and visualisation is quick and appropriate. Composite, easy to interpret maps can be produced at any size and printed or plotted at exact scales.

Interdex is complemented by the Coreview drill logging software package.
