It does :) http://trac.osgeo.org/grass/browser/grass-addons/imagery/i.topo.corr > Does anyone have a clue on how to do that? But i.topo.corr is a radiation correction, not a terrain correction in the sense of orthorectification. A rudimentary implementation was available in GRASS 4.x in the image3 library but that was not completely developed. We are looking for a developer (master student thesis?) to implement such an algorithm. Meanwhile you could check OSSIM which has some sensor models: http://download.osgeo.org/ossim/docs/pdfs/OSSIMOrthos.pdf Markus _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
