Replacing Grid Node Values from the Datasheet

RockWorks | ModOps | Grid | Filters | Replace

For each XYZ point within the RockWorks Datasheet, this program will locate the closest node within a grid file and replace its z-value with the z-value for the point within the datasheet. This can be a very handy way to "correct" grid models or even create grids based on imported XYZ points.

Step-by-Step Summary

Menu Options

• Data Columns: Use these prompts to define the columns within the datasheet which contain the X and Y (location) coordinates and the Z value to be "pushed" into the grid model.
  • 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.
  • Z (Elevation): Click here to select the name of the column containing the Z values (elevation, concentration, etc.) to replace node values in the existing grid.
  • 
    
• Grid Names
  • Input Grid: Click to the right to select the name of the existing grid file (.RwGrd) that the program is to read and filter.
  • Output Grid: Click to the right to type in the name to assign to the new grid file that the program will create, which results from the replacement filtering operation.

• 2D Grid Map
  Check this box to display the output grid as a 2D map at this time.
  Click this tab to set up the 2D map layers (bitmap, symbols, labels, line contours, color-filled contours, labeled cells, map border, etc.).
• 
  
• 3D Grid Diagram
  Check this box to display the output grid as a 3D surface at this time.
  Click this tab to set up the 3D map layers (surface colors, images, reference cage, etc.).
  ! You can request both a 2D and 3D representation of the grid model.

Step-by-Step Summary

1. Be sure you have a RockWorks grid model (.RwGrd file) already created, for input into this program. See Initializing Grid Models if you need to create a new, blank grid.
2. Access the RockWorks Datasheet program tab.
3. Open the .RwDat file that contains the XY point locations with the Z values to be used to replace the node values in the input grid.
4. Select the ModOps | Grid | Filters | Replace 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, locate the closest node to each XYZ point in the datasheet, and replace those nodes with the listed Z value. The resulting grid will be saved 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.

7. You can adjust any of the settings in the Options window and then click the Process button again to regenerate the diagram(s).
8. View / save / manipulate / export / print the diagram in the RockPlot2D or RockPlot3D window.
