Hi, I'm working on a terrain model. I have 7000 photos taken with the Phantom 4 pro. I have a working area of 5000m x 500m and 25 ground control points.
I think I'll do it faster if I make all the photos aero piece by piece. I'm thinking of merging the resulting blocks.
Do I have problems in merging between blocks?
I need to add gcp for each block and then merge it later, or should I add gcp after merging and do aero again. ?
thank you.
Divide it in smaller overlapping blocks and place GCPs in each so each block have at least some common GCPs with blocks between. Then at the end you will be able to simply merge all blocks as they will be in one coordinate system.
