I have a project where the east most GCP only hit the 5 pictures and at the edge of the picture. So I believe I did not have enough overlap. My elevation from the point cloud at this control point is off by 7 ft vertically. If I add manual tie points in this area that has enough overlap pictures Do I have to hit a known x,y,z point as a MTP? I fear that if I just pick a point it is grabbing the elevation from the point cloud which is off 7 feet vertically and then will adjust my other 7 control points which will make them off by roughly 4 feet.
Any help would be greatly advised.
