(115) Cosmetic (06/22/04:JPR):  The "Overwrite Options" within the File / Import / Into-Borehole-Manager / ASCII & XLS menus now appear as an "expanded" option (i.e. all options are shown within the initial display).  Also;  The default overwrite condition is to now "Create New File Name".  This will hopefully eliminate some confusion when importing data.

(114) Bug Fix (06/22/04:JPR):  File / Import / Into-Borehole-Manager / XLS:  The program now imports the descriptions for lithology intervals.

(113) New Feature (06/21/04:JPR):  A new program titled "Krajewskigram" has been added to the Geological-Utilities / Solid / Statistics menu.  This program, which is very similar to the Grid / Statistics / Krajewskigram program is used to show the differences between the original control points and a solid model (i.e. the "accuracy" of the model). 

The Krajewskigram program creates a scattergram depicting the observed (control point) "g" values versus the corresponding solid model node values.  It also computes the correlation coefficient and lists the result within the diagram title (assuming that the user has enabled the border annotation).  This number ranges between zero (no correlation) to 1.0 (perfect correlation). 

Note: The correlation coefficient provides a quantitative comparison between the observed data and the predicted model.  It does not reflect how reasonable the model is.  In other words; a model with a high correlation coefficient isn't necessarily good.  The following diagrams illustrate the relationship between the solid model resolution and the correlation coefficient.

As the model resolution increases, the correlation coefficient will also increase.  A scattergram depicting model resolution (number of solid model nodes - aka "voxels") versus the correlation coefficient will typically show a relationship illustrated within the red curve in the following example.

Notice how the correlation is very low for lower-resolution solid models.  As the resolution is increased, the correlation increases dramatically at first.  Subsequent increases in resolution have a less dramatic effect.  Notice that there is an inflection point at which the relationship between resolution and correlation begins to "flatten out".  We refer to this as the "point of diminished return".  Modeling beyond this point is questionable for several reasons;

• It increases the processing time (e.g. minutes versus days).

• Depending upon the algorithm, it may introduce "artifacts" (e.g. closed contours around nodes within inverse-distance models).

(112) Improvement (06/21/04:JPR): Project-Dimensions:  The "Clean-Data" option setting is now "remembered" by the program (i.e. it no longer always defaults to "true").

(111) New Feature (06/20/04:JPR): Geological-Utilities / Grid / Statistics / Krajewskigram:  The program now computes the correlation coefficient and lists the result within the diagram title (assuming that the user has enabled the border annotation).  This number ranges between zero (no correlation) to 1.0 (perfect correlation). 

Note: The correlation coefficient provides a quantitative comparison between the observed data and the predicted model.  It does not reflect how reasonable the model is.  In other words; a model with a high correlation coefficient isn't necessarily good.  The following diagrams illustrate the relationship between the grid resolution and the correlation coefficient.

As the model resolution increases, the correlation coefficient will also increase.  A scattergram depicting model resolution (number of grid nodes) versus the correlation coefficient will typically show a relationship illustrated within the red curve in the following example.

Notice how the correlation is very low for lower-resolution grids.  As the resolution is increased, the correlation increases dramatically at first.  Subsequent increases in resolution have a less dramatic effect.  Notice that there is an inflection point at which the relationship between resolution and correlation begins to "flatten out".  We refer to this as the "point of diminished return".  Modeling beyond this point is questionable for several reasons;

• It increases the processing time (not a big deal for grids but very important for solids).

• Depending upon the algorithm, it may introduce "artifacts" (e.g. closed contours around nodes within inverse-distance grids).

• It's obnoxious.

(110) Improvement (06/18/04:JPR): Geological-Utilities / Grid / Statistics / Krajewskigram:  The program now plots a linear -regression line rather than a polynomial fit to the data.

(109) New Feature (06/18/04:JPR): Borehole-Manager / I-Data / Export:  A new program called "Utilities Datasheet" will export all interval data for a selected track into the Geological Utilities datasheet.

• The "Everything" option will create a table that lists;

  • Borehole names.

  • Depth to top of interval.

  • Easting (X) at top of interval.

  • Northing (Y) at top of interval.

  • Elevation (Z) at top of interval

  • Depth to base of interval.

  • Easting (X) at base of interval.

  • Northing (Y) at base of interval

  • Elevation (Z) at base of interval.

  • Depth to midpoint of interval.

  • Easting (X) at interval midpoint.

  • Northing (Y) at interval midpoint.

  • Elevation (Z) at interval midpoint.

  • Magnitude (e.g. geochemistry).

• Conversely, the "Midpoint" option will only list the XYZG information for the interval midpoint;

This program is useful whenever you wish to perform subsequent analyses on all of the borehole data for a selected I-Data track.  For example, if you wanted to view a histogram for all of the Benzene data within the Borehole Manager, you would run this export/transfer utility and then select the Stats / Histogram option in order to produce the following diagram;

Also keep in mind that the program will only export data for "enabled" boreholes.  This provides a means for evaluating data within selected groups of boreholes as well as individual boreholes.

(108) Cosmetic (06/18/04:JPR): Geological-Utilities / Grid / Statistics:  Icons have been added to all menu options.

(107) New Feature (06/17/04:MIW): Borehole-Manager / Stratigraphy / Pick-Contacts:  A new button has been added for transferring the current display into the RockPlot/2D program.

(106) Bug Fix (06/12/04:MIW): Programs that read XYZ data from ASCII space-delimited files no longer have problems when reading lines of data that are incomplete (e.g. missing data columns).  Also; the last character of a line is no longer skipped.

(105) Improvement (06/12/04:MIW): ReportWorks:  The program no longer uses the RWSymbols.dll and RWPattern.dll files.  This improves the stability of the program (less DLLhell).  These files have been removed from the installation program.

(104) Bug Fix (06/12/04:MIW): RockPlot/2D / Import / Shape:  The program now properly imports ESRI shape files.  The previous version ignored some of the menu settings.

(103) New Feature (06/12/04:MIW): ReportWorks:  The program now includes an option for plotting color legends.

(102) New Feature (06/12/04:MIW): ReportWorks:  The program now includes an option for plotting symbol legends.

(101) New Feature (06/12/04:MIW): Geological-Utilities / Grid / Statistics / Report:  The "center of mass" coordinates are now included within the report. 

(100) New Feature (06/12/04:MIW): Geological-Utilities / Solid / Statistics / Report:  The "center of mass" coordinates are now included within the report.

(99) New Feature (06/12/04:MIW): RockPlot/2D / Utilities / Degrees->UTM:  A new option has been added for exporting the data in footage units (versus meters).

(98) New Feature (06/11/04:JPR): Geological-Utilities / Volumetrics / Extract-Solid:  A new option titled "Optimize" has been added to the menu.  If activated, this option will start by computing the configuration for a pit that extracts all of the material within the specified grade range.  It will then decrease the maximum pit depth (by the increments specified by the "Depth Increment" setting) until the stripping ratio is equal to or less than the specified "Maximum Acceptable Stripping Ratio".

(97) New Feature (06/11/04:JPR): Geological-Utilities / Volumetrics / Extract-Solid:  The contaminant/ore-body (as shown by an isosurface) within the output now exists as a continuous solid rather than a boolean model.  This means that the user may now adjust the isolevel value.  The node values above the ground surface are set to zero.

(96) New Feature (06/11/04:JPR): Geological-Utilities / Volumetrics / Extract-Solid:  The program now includes an option that allows the user to specify if "benches" should be used within the excavation pit.  If selected, the user may specify the height of these benches. 

(94) New Feature (06/08/04:JPR): Geological-Utilities / Volumetrics / Extract-Solid:  The program now includes an option that allows the user to specify a "buffer" around the perimeter of the ore/contaminant nodes such that the entire voxel will be removed (versus just a pit that encloses the node).  This is accomplished by enlarging the excavation pit such that there will be a one-voxel border around the lateral sides of each voxel.

(93) New Feature (06/08/04:JPR): Geological-Utilities / Volumetrics / Extract-Solid:  The program now includes an option that allows the user to specify the maximum slope angle for the excavation surface (pit).

Note: Slope angles must be expressed in negative degrees from -90 to zero.  For example, -90 = vertical walls.

(92) New Feature (06/08/04:JPR): Geological-Utilities / Volumetrics / Extract-Solid:  The program now includes options that allow the user to specify the maximum extraction depth relative to the surface.  This setting is also shown (if enabled) within the statistical report.

(92) New Feature (06/08/04:JPR): Geological-Utilities / Volumetrics / Extract-Solid:  The program now truncates (sets node values to zero) any voxel values above the ground surface.

(91) Bug Fix (06/08/04:JPR): Geological-Utilities / Volumetrics / Extract-Solid:  The program now computes the maximum pit depth relative to the ground surface rather than the top of the solid model.

(90) Cosmetic (05/28/04:JPR): The program no longer generates a "The project dimensions have been defined..."  message when running an RCL script and accessing a project folder that does not have an initialized copy of the RW_Project.txt file (i.e. the file where the project dimensions are stored).

(89) Cosmetic (05/27/04:MMM): The Geological-Utilities / Grafix / 2D-Utilities / Convert-RockPlot2D / TIFF program now displays the correct embedded documentation.

(88) New Feature (05/27/04:MIW): When launching an RCL script file from outside of RockWorks (i.e. from another program or from Windows Explorer), the status dialog may be disabled by including a "/HIDE" command as the second command line parameter.  For example;

C:\Program Files\RockWare\RockWorks2004\RW2004.exe c:\project_27\xsect01.rcl /hide

The /Hide parameter is case insensitive (e.g. "/hide" and "/Hide" are ok). 

Note:  There must be at least one space between the name of the RCL file and the /Hide parameter.

The default setting is for the program to display the status messages, meaning that if the /Hide parameter is omitted, the program will display the status dialog.

The RCL "HIDE:" command has been consequently removed (see item #74).

(87) New Feature (05/27/04:MIW): The ReportWorks program now includes utilities for exporting to PNG files.

(86) Bug Fix (05/27/04:MIW): The RockPlot2D / Export raster-based utilities now uses the vertical exaggeration factor correctly.  The previous version would ignore it.

(85) Bug Fix (05/27/04:MIW): The Geological-Utilities / Grafix / RockPlot2D -> EMF menu now displays correctly.

(84) New Feature (05/27/04:JPR): A new option titled "RCL Format" has been added to the View / General-Preferences / Create-Menu-Summaries sub-menu.

This new option will create menu summaries that may be directly copied and pasted into RCL scripts.

(83) Improvement (05/27/04:JPR): If an RCL script encounters a fatal error, the source file (i.e. the RCL script file) is now "unlocked" so that the user may re-save the file without terminating RockWorks.

(82) Improvement (05/27/04:JPR): The previous version of the RCL (RockWorks Command Language) would always insert the project folder path to the beginning of any file name.  The program now skips this step if a forward-slash character ("/") already exists within the file name (i.e. a path other than the project folder is specified).

(81) Bug Fix (05/25/04:JPR): The installation program now allows the user to install the program into a drive other than the C-drive.

(80) New Feature (05/25/04:JPR): The Geological-Utilities / Solid / Initialize program now allows the user to create models with randomly generated g-values.

(79) Improvement (05/24/04:JPR): The Geological-Utilities / Util / Finance / Loan-Analysis program report now includes the principal, interest rate, loan-duration and payment amount.

(78) Bug Fix (05/21/04:MMM): The installation program now includes the following RockPlot/3D sample files;

• Rp3dt_benzene.xml

• Rp3dt_logs.xml

• Rp3dt_surfaces.xml

(77) Bug Fix (05/21/04:MIW): The Geological-Utilities / Solid / Fracture-Discs -> Solid program now works correctly.

(76) Bug Fix (05/18/04:JPR): Borehole-Manager / Lithology / Surface-Map:  The program now calculates the correct lithology.  The previous version was completely wrong and predicted lithology well below the surface model when using surface models that do not represent the ground surface.

(32) Cosmetic (04/22/04:MIW): Geological Utilities / Grafix / Images / Digitize-From-Bitmap:  The menu is now properly maximized upon startup.

(31) Cosmetic (04/17/04:MIW): Geological Utilities / Util / Compile RCL File:  The program now refreshes the screen after a batch process has been executed.

(30) Bug Fix (04/16/04:MIW): Geological Utilities / Map / LandGrid / Section Map:  The program now plots section labels even if the section acreages are not included.

(29) Bug Fix (04/14/04:MIW): Geological Utilities / Coords / Jeffersonian Points -> Cartesian:  The program now work correctly.  The previous version was incorrectly reporting the projection intersections thereby omitting points.

(28) New Feature (04/14/04:MIW): Borehole Manager / Stratigraphy / Pick-Contacts:  The spacing between the logs may now be switched from proportional (i.e. relative to the distance between the boreholes) to a uniform spacing that is either manually, or automatically computed.

(27) New Feature (04/14/04:MIW): Borehole Manager / Stratigraphy / Pick-Contacts:  The cursor elevation is now displayed within the main dialog caption.

(26) New Feature (04/14/04:MIW): Borehole Manager / Stratigraphy / Pick-Contacts:  The program now plots the logs, by default, at their appropriate structural elevations (i.e. relative to sea level). 

A new option titled, "Hang From Top of Borehole" will adjust the log elevations such that the top of the logs (zero depth) align to a horizontal datum.

This new capability to plot by elevation allows the user to include projected picks above and below existing logs.

(25) Improvement (04/14/04:MIW): Borehole Manager / Stratigraphy / Pick-Contacts:  The number of boreholes that can be handled by the program is now unlimited (the previous version was limited to 100 boreholes).

(24) Bug Fix (04/14/04:MIW): The RockPlot3D program no longer generates sporadic errors when generating stratigraphic models.

(23) Bug Fix (04/14/04:MIW): The ReportWorks program no longer generates an Out-of-Resources error if the user zooms into a RockPlot image more than 500% (i.e. the program now limits the zoom to 500%).

(22) Bug Fix (04/14/04:MIW): The RockWorks -> DXF export  program now properly exports polygons (the previous version was including extra vertices).

(21) Bug Fix (04/14/04:MIW): The RockWorks -> DXF export  program no longer uses the multi-layer options when creating a single-layer DXF file.

(20) Bug Fix (04/14/04:MIW): The "Clean" option within the Project Dimensions menu now computes the proper y-max when computing the range of data.

(19) New Feature (04/14/04:MIW): The Project Dimensions menu now allows the user to specify if the model resolution should be based upon the average minimum distance between control points versus a fixed number of nodes.

(18) Bug Fix (04/14/04:MIW): The border annotation options for plotting horizontal and vertical borders are no longer switched.

(17) New Feature (04/14/04:MIW): The polygon table editor now allows the user to specify the line type and fill style when plotting the polygon.

(16) Improvement (04/14/04:MIW): The program now plots boreholes in which the PData or IData have a range of zero and the scaling is set to automatic (i.e. it simply doesn't plot that data rather than generating an error message).

(15) Improvement (04/08/04:JPR): The program that imports XLS (Excel) data into RockWorks now provides meaningful warnings if the I-Data or P-Data column titles are not defined either within the Excel worksheet or an existing list.  The previous version would generate a fatal error.

(13) RockWorks/2004 Beta - New Feature (04/06/04/JPR): The Comments section within the Borehole Manager Locations tab now includes horizontal and vertical scroll bars.

(12) RockWorks/2004 Beta - New Feature (04/06/04/JPR): The Comments section within the Borehole Manager Locations tab now positions the cursor at the top of the comment section whenever the active borehole is changed.

(11) RockWorks/2004 Beta - Bug Fix (04/05/04/MIW): The solid modeling program now applies the high-fidelity filter before applying the strata-bound filtering.  In the previous version, the high-fidelity filter would cancel the effect of the stratabound filter.

(10) RockWorks/2004 Beta - Bug Fix (04/05/04/MIW): The Borehole Manager data grids now change color after the Configure option has been completed.

(9) RockWorks/2004 Beta - Cosmetic (04/05/04/MIW): The "Bitmap" tab within the Borehole Manager has been renamed to "Images".

(8) RockWorks/2004 Beta - New Feature (04/05/04/MIW): If the program is set up for manual log compilation, and the use changes to a project folder that does not already include compiled binary files, the program will automatically create them.

(7) RockWorks/2004 Beta - New Feature (04/05/04/MIW): If the program is set up for manual log compilation, the user can now switch folders and use the existing compiled files.

(6) RockWorks/2004 Beta - Cosmetic (04/02/04/MIW): The "anisotropic" and "isotropic" options within the solid-modeling algorithm menus have been switched.

(5) RockWorks/2004 Beta - Cosmetic (04/02/04/MIW): The log-clipping sub-menu now lists the "Top Elevation" and "Base Elevation".

(4) RockWorks/2004 Beta - Bug Fix (04/02/04/MIW): Partially-clipped pattern intervals now plot the caption correctly within 3D logs.

(3) RockWorks/2004 Beta - Bug Fix (04/02/04/MIW): Curve and bar-graph background grids are now clipped correctly within 2D logs.

(2) RockWorks/2004 Beta - Improvement (04/02/04/MIW): The clipping within 3D boreholes now truncate (rather than remove) lithologic, and stratigraphic intervals.

(1) RockWorks/2004 Beta - Improvement (04/02/04/MIW): Bitmaps are now clipped within 3D boreholes.
