I would like to know does gdalwarp uses the z coordinates of CGP data for georeferencing the raw tiff image. If yes, the is it possible to use the DEM data thecorrection of image relief in hilly terrain.
S.Subramaniam, No, the gdalwarp polynomial and thin plate spline transformers do not make any use of the gcp Z's at this time, and there is no mechanism provided for correction based on image relief in hilly regions. OSSIM might have such a capability.
