Hi! I'm trying to perform some topo correction on Landsat TM and ETM+ data using ASTER DEM (30m) or SRTM DEM (90m). I already used Atcor 3 module for Erdas 2013. But i'm not satisfied with results (it performs topo and atmospheric correction, but I need only topographic). Can You recommend me some software or a method to make topographic correction? I made a script in python for DOS atmospheric correction (its best in my case, i'm going to make change detection on vegetation indices) and its a mountain area so topo correction is required.. Best regards Rutek
