For this project, I have used 4 GCPs. I find that after processing, the GCP location (marked in black and white in the image below) has been shifted from the place it should be (the red cross location) by -0.9 in the X direction and by -0.4 in the Y direction… I don’t quite understand this… The red cross now has the coordinates of the manually entered black and white GCP coordinates, but in return, this black and white GCP is now shifted from its original location…
Why does this happen? What does it mean?
Does it mean my orthophoto and point cloud are inaccurate by -0.9 and -0.4 ?
