Virtual Surveyor can help you to align your photogrammetry outputs with your elevation datum.
The proper elevation datum needs to be set in your photogrammetry process. That is the processing step before you start working in Virtual Surveyor. Nevertheless, most of the time your image processing software only exports Ellipsoidal height unless you use GCPs or adjust the 3D model to a global or local geoid model.
Virtual Surveyor provides a quick and easy way to adjust your data to local heights.
Adjust Your Terrain Elevation
- Import the survey dataset.
- Select the elevation terrain file in the Project View layers and go to the TOOLS tab.
- Set the offset Z value in the Offset group.
- Press Enter.
- The elevation terrain is moved up or down according to the offset value.
