Hi all, I have added thin plate spline coordinate transformation to i.rectify, needed for e.g. level 1 B satellite imagery such as NOAA AVHRR or ENVISAT MERIS, or maybe also historical maps with unknown but serious geometric distortions.
Additionally I have modified r.in.gdal a bit: previously it exited with a fatal error if the specified target location (Name of location to read projection from for GCPs transformation) did not exist. Because an input xy raster can have GCPs with their own valid projection information, r.in.gdal will now create this target location if not existent, using the projection information of the GCPs (not the raster). That also means that if the target GCP location did not exist, the imported raster maps can now be georectified straight away with i.rectify, using the embedded GCPs. The behaviour with regard to r.in.gdal's location option (using the raster's projection info) is unchanged.
