Hi Chris, there is something wrong witj your input elevetation parameters : -elev.default 272 -elev.dem /.../DEM_Directory -elev.geoid /.../egm96.grd
you should use either elev.default to set elevation to default value , or eleve.dem and elev.geoid to handle DEM, Jonathan 2014-08-13 5:29 GMT+02:00 Chris <[email protected]>: > Hi Jonathan, > > Thank you for the reply. > > If extracROI is the right way to crop the image, then why my entire image > can be successfully matched, whereas the subset image extracted by " > extractROI" cannot match? > > If the entire image and its subset share a same RPC file, but with > different origins, then how OTB can recognize that the image has been > changed?
