For a Water Overlay, the watertable can be defined by a groundwater prequel. GeoTIFF Overlays can be used as a prequel for either the groundwater level relative to the surface (i.e. the depth) or relative to datum (i.e. the height).

Editor → Current Situation (Ribbon tab) → Overlays (Ribbon bar) → The Water Overlay (Left panel) → Configuration Wizard (Right panel)
How to add your own GeoTIFF with groundwater data to the Water Overlay:
  1. Prepare a GeoTIFF file with the desired watertable depths.
  2. Open the configuration wizard of the Water Overlay.
  3. Continue to the step concerning ground water.
  4. If your GeoTIFF features groundwater depths, opt for "Select a Grid Overlay as Groundwater Depth".
    If your GeoTIFF features groundwater heights relative to datum, opt for "Select a Grid Overlay as Groundwater Level (Datum)".
  5. Click on "Add new GeoTIFF Overlay". The "GeoTIFF selection" window will open.
  6. Select "Add local file", locate your file and select it. This will automatically upload the GeoTIFF to your project.
  7. Now find and click on the added geotiff in the "GeoTIFF selection" window, and click on "Select" to confirm.
  8. Close the wizard.

  • Select one of the advanced steps to show the option to Add new GeoTIFF Overlay

  • Add local file and select the GeoTIFF once uploaded to your project.
