Use interval data for formation tops or ore grade in Voxler

KB no longer maintained - Voxler is a retired product. Golden Software retired products are still supported, but no longer receive new features or updates. Many of Voxler's features are moving to Surfer . Please contact with any questions.
One way to create a geological model in Voxler is to assign a numerical value to each layer interval, grid the data, and attach a VolRender module (fill color) and multiple Isosurface modules (one for each layer to show the layer tops). For instructions on how to do so, see the example below. This example will begin from a single data file that containing an Easting column, a Northing column, an Elevation column, and a Layer column for multiple wells. 


  1. If the depth intervals are large, split them out into smaller intervals that will allow you to see the level of detail you desire, then replace the layer name with a layer number (i.e. here Anuvium = 1, Dakota Formation = 2, and Morrison Formation = 3).
  2. Repeat the previous step for all boreholes in the file and then save the file.
  3. In Voxler, click File | Import.
  4. In the Import dialog select the data file and click Open.
  5. If the data file is an XLSX file, in the XLSX Import Options dialog, select the sheet name and click OK.
  6. Right click on the data module in the Network Manager and click Computational | Gridder.
  7. Select the Gridder module in the Network Manager and click on the General tab in the Property Manager.
  8. Set the gridding parameters (apply gridding and search anisotropy if the XY range is much larger than the Z range). Hint: Specify a smaller Z interval for more grid lines in the Z direction and better resolution.
  9. Click the Begin Gridding button.
  10. Right click on the Gridder module in the Network Manager and click Graphics Output | Isosurface
  11. Set the Isovalue in the Property Manager to a value just short of your second Layer # (i.e. 1.99 for a Layer # of 2) to show the top of the second formation. 
  12. Repeat steps 10-11 for the other layers.
  13. Right click on the Gridder module in the Network Manager and click Graphics Output | VolRender
  14. Edit the Colormap settings in the Property Manager to fill each layer with a specific color.
