Have tried this many times where I am generating several files from a flight with surveyed ground control points. Creating DTM, DSM models and an ortho photo. Also, contours in a .dxf formation from both DTM and DSM. However, whenever I upload the contour data and ortho into Microstation it is always shifted by a few feet. The contour data appears to be accurate as it matches the GCPs but the imagery is always shifted. Don’t seem to have this problem in GIS software though, they match up nice. Any help is appreciated.
