Photogrammetry is a memory and compute intensive process. You typically need a very powerful computer with a lot of memory to get your job done. Even with a good system, the processing time can take very long and tends to increase exponentially with the number of pictures you add to your photogrammetry project. Also cloud photogrammetry solutions have limitations on the number of pictures they can process. 

  Hint! Process your project in smaller chunks or blocks and merge these different blocks together to one large project in Virtual Surveyor.

Virtual Surveyor has the following tools available:

  • Set the order of the different image and elevation terrains. This functionality allows you to control exactly what terrain is on top over the other when they overlap.
  • Create clean seams between the different blocks with the clipping tool.
  • Optionally export your mosaic to one combined GeoTIFF or JPEG2000 file. However, we recommend to create your survey, contours or TIN on the virtual mosaic and to export those data to a CAD compatible file format (.dxf, xml, ...).

You can create virtual mosaics that are maximum 250 km (155 miles) in any direction.

Set order

  • You can change the order of a terrain with Move Up or Move Down.
  • These buttons appears when you have selected at least an image or elevation terrain.
  • Click Move Up or Move Down to change the order of the terrain compared to the other terrains.

Clip with boundary

  • The Clip button appears in the contextual SELECTION tab when you have a terrain AND a boundary selected.
  • Click Clip to trim the selected terrain to the selected boundary.


  • The Export Terrain button is available in the EXPORT tab
  • Create a boundary for the total area you want to export
  • Click Export Elevation to .tif or Export Image to .tif in order to export the virtual mosaic to a terrain file.

Info! Export Elevation Terrain is not supported in Valley
