Mavic 2 Pro DEM result out of

[masopiq]

I hope someone could help me..
I did aerial mapping with Mavic 2 Pro to get contour, my flight setting altitude 220m, speed 12 m/s, overlap 80% sidelap 60%. DEM result have difference elevation about 1-3 meter even if at GCP. Iam using 5 GCP for and already enable full rolling shutter compensation before align...
Is there any missing step in processing ?

Thanks in advance

After identifying all GCPs, are you disabling the camera positions before the optimizing step?  The elevation reported in the image exif is junk.
