I’m having tremendous difficulty generating consistent surface data.
To briefly summarize, I have:
Flown multiple flights over the same location
Set GCPs using survey grade GPS equipment.
Independently processed individual flights using same GCP points.
Found significant surface variations (Z values) where no surface change has occurred between flights.
Can anyone please explain the variation between surface data? I’ve tried to limit as many external factors as possible (Used same .afp mission for all flights, flights conducted under similar weather conditions and wind direction, similiar # of photos used for processing, etc.).
