We often get the question if Virtual Surveyor can produce an orthophoto or elevation model from a set of pictures that have been acquired with an unmanned aerial system.


Where are we in the value chain?


A typical UAV value chain for survey projects consists of three steps:

  • Step 1: Acquire pictures with your drone
  • Step 2: Produce orthophotos and elevation models with a photogrammetry package
  • Step 3: Visualize, analyze and interpret your data with Virtual Surveyor

Virtual Surveyor is located in the 3rd step of this value chain and requires orthophotos and elevation models that are already created by dedicated software photogrammetry software packages. 

Good photogrammetry software packages are
