Dear GDAL community, I use the RPC transformer available in GDAL (GDALCreateRPCTransformer and GDALRPCTransform).
To provide a DEM to the transformer, one needs to set the option "RPC_DEM" with the path to the DEM file. In my workflow, this is not very convenient because the DEM is already loaded in memory as a GDALDataset. This means that I need to write it to the disk and let GDALCreateRPCTransformer load it again. In my opinion, it would make sens to open a little the API so one can provide the DEM directly as a GDALDataset. If this is OK for you, I can implement this functionality and propose a Pull Request. The solution I see would be to add a function GDALRPCAddDEM, similar to GDALRPCOpenDEM without the part opening the GDALDataset. What do you think? Best regards.
