That would be the altitude of the POI with respect to your take-off location. It is used to calculate the gimbal pitch angle so that the POI is centered vertically in the view of the camera
You are expected to estimate the altitude of the POI...

While this is an interesting and worthwhile pursuit, the ability to do this already exists in one of my converters.
The GPS coordinates, height, yaw, and gimbal pitch angle are also found in the flight log along with either a 0 (zero) or 1 (one)...
