After cleaning up your drone data with Virtual Surveyor, the Export Elevation tool allows you to deliver a part of the elevation terrain as a new Digital Elevation Model (DEM).



The Export Elevation tool is available in the EXPORT tab.


Overview


How to Export the Elevation Terrain

  1. Draw a boundary around the area you want to export.
  2. Select the boundary.
    1. Optional: Enable terrain modifiers to export the cleaned-up elevation terrain.
  3. Go to the EXPORT tab.
  4. Click on Export Elevation.
  5. Specify a filename and a folder location, then click Save.


Export the Elevation Terrain

Use Export Elevation to create a DEM that was cleaned up using workflows like Remove Object, Replace Terrain, Modify Terrain or remove vegetation. The resulting DEM can be used in a GIS software.

  • Showing the cleaned terrain by enabling the modified terrain of the conveyor belts in the Virtual Surveyor app with and without the Orthomosaic. Once removed, you can export the terrain as a DEM.
    Creating a DEM from cleaning the terrain by removing conveyors with the Orthomosaic disabled.


  • Showing the DEM with the conveyor belts in GIS software and the second image with them removed.

  • You can also use the Export Elevation feature to cut out a specific area from a very large DEM. The clipped elevation terrain can be shared with colleagues and customers or used to create a new Virtual Surveyor project that takes up less file space.


Tips & Tricks

  • You can combine Export Elevation with Export Image on the same area to generate a new and lighter dataset. 
  • The exported DEM is a GeoTIFF.
