[gdal-dev] RPC and DEM = Too many points (441 out of 441) failed to transform

Fri Jul 8 07:12:48 EDT 2011

Chris,

This could happen when you try to transform an image that is outside the
defined area of the destination projection.
Cut the raster to the destination projection's extents and try again.

There is a thread with exactly the same error message in the archives[1]. I
am not sure that it can help with your case, but try it anyway.
