Hello, my 3D RMS error is about 40 metres( !!!), 1m in horizontal and about 38 in vertical and my points imported coordinates turn red after locating all my controls (3 or 4 for each point). Why is it so bad? What am I doing wrong?
what type of camera using? its effect to RMS if using small camera or VDO camera due to the shutter effect , to improve RMS use GCP with GNSS.
