RockWorks17 GeoBody (Contiguous Voxels w/Same G-Value) Filter Improved

(014-017) Improvements (04/06/16/JPR): The following changes have been made to the Utilities | Solid | Filters | GeoBody Filter programs:

  • (014) Improvement: The minimum number of voxels setting that was used to remove small geobodies has been replaced with the Minimum % of Voxel Volume which is far more intuitive and universal.


  • (015) New Feature: The Contiguous Units Report now includes a column that shows the percent of the model (by volume) represented by each geobody.


  • (016) New Feature: The Contiguous Units Report is now automatically sorted in descending order based on the geobody populations (see example above).

     

  • (017) Bug Fix: The program no longer includes small disconnected geobodies as parts larger geobodies when processing very large models.


RockWorks17 Find, Find Next, & Find & Replace

(011-013) Improvements & New Feature (04/04/16/JPR): The DataSheet | Search | Find & Replace option has been split into three separate options:

  • (011) Find: This is the same as the previous Find & Replace | Highlight Cell option.  It has been moved into a separate dialog to minimize the chances of replacing something when only a search was required.
  • (012) Find Next:  This new feature repeats the previous Find operation at the row below the previously found item.  The F3 shortcut greatly speeds up the process of finding additional occurrances.
  • (013) Find & Replace:  This is essentially the same as the previous Find & Replace without the Highlight-Only option (which is now accomplished with the new Find operation.


New Solid -> Grid Conversions Added to RockWorks17

(003-008) New Features (04/02/16/JPR): The Conversion Types within the Utilities | Solid | Convert | Solid -> Grid and Solid -> Zones programs have been significantly enhanced:

  • (003) The conversion types have been moved from the tree-style menu into a new dialog box in order to incorporated explanatory text and four new conversions.


  • (004) A new Median conversion has been added. Select this option to compute the median node G value in each vertical column of the solid model, and store that G value in the corresponding grid node. The statistical median is the number separating the higher half of the sampling from the lower half. It is often a better representation of the “average” (versus the mean) when a distribution is skewed by outliers.
  • (005) A new Most Frequently Occurring G-Value conversion has been added. Select this option to compute the most frequently occurring node G value (the mode) in each vertical column of the solid model, and store that G value in the corresponding grid node. Note: This doesn’t work well for multimodal populations (i.e. vertical columns where there are “ties” for the most frequently occuring G values). In these cases, the program will arbritarily choose the first candidate. Also note that selecting this option will require significantly more time for performing the solid-to-grid conversion.
  • (006) A new Number of Non-Null Voxels conversion has been added. Select this option to count the number of non-null (>-1.0e26) G values in each vertical column of the solid model, and store that count in the corresponding grid node.
  • (007) A new Number of Null Voxels conversion has been added. Select this option to count the number of null (=-1.0e27) G values in each vertical column of the solid model, and store that count in the corresponding grid node.
  • (008) A new Standard Deviation conversion has been added. Select this option to compute the Standard Deviation of all the non-null nodes within each version column of the solid model, and store that count in the corresponding grid node. With some data sets, this number is an approximation of the vertical anisotropy (i.e. square root of variance).

The example below shows how these new conversions apply to an interpolated block model of Lead concentrations:


RockWorks StripMap Menu Redesigned

(279) Cosmetic (04/01/16/JPR): The options within the “Include StripMap” tree-menu have been re-designed as a separate dialog (accessed by clicking the new “Options” button adjacent to the “Include StripMap” checkbox) in order to incorporate graphic examples within the menu.
