I am processing a small project with 4 GCPs I created in GIS using existing features on the ground. After I mark the GCPs and run step one my GCP accuracy error is roughly 1m. When I go to edit the GCPs before reoptimization my GCPs appear to be shifted in different directions. I have attached images showing how the software determined GCP is inconsistently shifting.
I have double checked the accuracy of my points in GIS and they look good.
Imagery was gathered with a DJI Phantom 4
Image coordinate system is WGS 84
GCP coordinate system is WGS/Pseudo-Mercator
Output coordinate system is WGS/Pseudo-Mercator
