The height in the report is the top of the AeroPoint. That’s the point you use in the georeferencing process when you have the AeroPoint in the survey images.

If you’re processing images that instead contain a stencil mark or ground marker (ie the point the AeroPoint was placed over), you need to subtract the thickness of the AeroPoint (32mm) from the report height. You can download the survey report in CSV format and use Excel to subtract 0.032m (or 0.105ft) from the elevation you use.

Note that if you use Propeller’s cloud processing, we’ll handle this for you.
