Hi,
We are trying to use the othomosaic workspace to ortho rectify a Pleiades imagery in the DIMAP format. There are RPC, but we whish to add GCP. The problem arise when we want to process, it gives us a warning:
Cannot find a valid horizontal datum transformation from spatial reference of the Digital Elevation Model (WGS_1984_3D) to spatial reference of the Sensor Model (GCS_WGS_1984 / VCS: WGS_1984).
Our DEM is actually in WGS 1984 and yes it has ellipsoid height, so WGS_1984_3D is correct. And for sure, the iamgery should also be in WGS 1984, both horizontal and elavation as said by the message. So from my point of view those 2 are the same, so why do I get a warning... And most of all, how can I determine if it had sucessfully applied the DEM "correction"?
Any hint would be greatly appreciated.
