Coordinate transformation incorrect

General Feedback & Requests

Hi,

I have processed a dataset acquired with a DJI Matrice 4E drone, RTK was used during acquisition. I’ve used the coordinates from the EXIF headers for georeferencing, which appear to be identical to those in the .MRK file. I use the Dutch coordinate system (EPSG:7415) as project and output coordinate system. Unfortunately, all output is shifted by approx. 120 meters with regard to reality. The original image coordinates (which are in WGS84 or ETRS89) are in the correct location if transformed within QGIS. This leads me to believe that the transformation from WGS84/ETRS89 (I’ve tried both) to EPSG:7415 is not performed correctly. Have others noticed similar issues with the same or other projected output coordinate systems?

Hi Toby,
what kind of exports have you provided? In which way are the outputs shifted? Have you had set the Project output setting also in the export settings? Also, can you try to use just 28992 Amersfoort / RD New system, as RealityScan doesn’t support geoid heights?
