I’m having some issues forcing the Z value to the absolute elevation corresponding to the GCPs. To give a bit of backstory;
- I map the flight, fly the drone and upload photos importing GCPs and making sure that I use the right coordinate system (OSGB)
- When everything is processed I calibrate the map if required so the ‘elevations’ tab shows elevations that tie in with my GCPs
- If I export to a DTM (.dxf) or point cloud (.las) the X & Y co-ordinates tie in with the GCPs but the Z co-ordinates (elevations) don’t
I’m also making sure that any files i export are in the coordinate system i’m using. I’m trying to use the drone topos for surface creation in Civ 3D so it’s kind of vital that the elevations actually tie in - does anyone have any idea as to why it’s not working?
