RockWorks | Utilities | Grid | Filters | Smooth
This program reads an existing grid file (.RwGrd file) and averages the Z-values based on a user declared "filter" size. The smoother can be run 1 or more times, to get rid of spurious "noise" within the grid model and bring out regional trends.

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 select 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 smoothing operation.
- Filter Size: This setting defines how many adjacent nodes should be used when computing the average (smoothed) Z-value for each grid node. If you enter "1", then each node will be assigned the average of itself and the 8 nodes immediately surrounding it, 1 layer deep. If you enter "2", the node will be assigned the average of itself and the 24 nodes immediately surrounding it, 2 layers deep. When in doubt, enter "1".
- Iterations: Enter the number of times the entire model should be run through the smoother.
- 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
- Be sure you have a RockWorks grid model (.RwGrd file) already created, for input into this program.
- Access the RockWorks Utilities program tab so that you can see the Grid menu commands.
- 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.
- Select the Grid | Filters | Smooth menu option.
- Enter the requested menu settings, described above.
- Click the Process button to proceed.
The program will load the input file, compute the new value for each grid node using the requested filter size. This process will be repeated for each node in the entire source model. If Iterations was set to >1, the entire model will be passed though the "smoother" for the requested number of times. The resulting node values will be stored in a new grid file on disk under the output file name you selected.
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.
- 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.
- View / save / manipulate / export / print the diagram in the RockPlot2D or RockPlot3D window.
