A colleague of mine has run into an issue of Pix4D desktop creating overlapping surfaces. He and I worked on the problem together yesterday, but could find no glaring errors. There are four flights using a Phantom 4 Pro at 400ft. 80% overlap.
Where the 4 flights overlap Pix4D is creating two identical surfaces. The surfaces are identical except for they are separated vertically by 10 to 60 feet. The project has sufficient GCPs that were surveyed in with survey grade GPS. No issues with the GCPs were noticed.
Anyone come across this before or have any recommendations?
