Applying a Rounding Filter to a Grid Model

RockWorks | Utilities | Grid | Filters | Round

This program reads Z-values stored in a grid file and rounds them up or down to the user-declared Z-value rounding interval.

Step-by-Step Summary

Menu Options

• Input Columns:  If you request plotting of 2D map symbols (below) AND if you have data loaded into the Utilities datasheet, you can use these prompts (along the left edge of the Options window) to specify the X and Y locations for the map symbols.  If you don't plot map symbols, these will be ignored.
  • X (Easting): Click here to select the name of the column containing the X or Easting  coordinates.
  • Y (Northing): Click here to select the name of the column containing the Y or Northing coordinates.
    
    
• Input Grid Model: Click to the right to browse for the name of the existing grid file (.RwGrd) that the program is to read and manipulate. 
• Output Grid Model: Click to the right to enter the name to assign to the new grid file that the program will create, which results from the rounding operation. 
  
  
• Rounding Interval: Enter the Z-value interval to which grid nodes are to be rounded. For example, if you enter "10" and the Z-values represent feet, then all grid nodes will be rounded to the nearest 10-foot interval. 
  
  
• Create 2-Dimensional Grid Diagram: Insert a check in this check-box if you want to display the output grid as a 2D map at this time.  Expand this heading to set up the 2D map layers (bitmap, symbols, labels, line contours, color-filled contours, labeled cells, and/or map border).
• Create 3-Dimensional Grid Diagram: Insert a check in this check-box if you want to display the output grid as a 3D surface.  Expand this heading to set up the 3D map layers (flat surface, Boolean colors, perimeter, reference cage).  You can request both a 2D and 3D representation of the grid model.
• Create Grid Statistics Report: Insert a check here if you want to see a report summarizing the output grid. 
  • Include Standard Deviation:  Check this box if you want the report to include standard deviation.
  • Include Directional Analysis:  Check this box to include slope, aspect, and strike computations. Be warned that these can take a few moments for large grid models.
     

Step-by-Step Summary

1. Be sure you have a RockWorks grid model (.RwGrd file) already created, for input into this program.
2. Access the RockWorks Utilities program tab so that you can see the Grid menu commands. 
3. If you'll be creating a 2D map with sample location (well) symbols, use the File | Open option to open the .RwDat file containing the X and Y location coordinates for the map symbols.  
4. Select the Grid | Filters | Round menu option. 
5. Enter the requested menu settings, described above.
6. Click the Process button to continue. 

The program will load the input grid file, round each grid node Z-value to the nearest rounding interval, and store the results on disk under the output grid file name.

The requested diagram(s) will be displayed in a RockPlot2D tab and/or RockPlot3D tab in the Options window.   If you requested a statistics report, it will be displayed in a Text Tab in the Options window.

7. You can adjust any of the settings in the Options window and then click the Process button again to regenerate the diagram(s).
   ! Each time you click the Process button, the existing display(s) will be replaced. 
    
8. View / save / manipulate / export / print the diagram in the RockPlot2D or RockPlot3D window.
