Topographic correction of Landsat imagery using GRASS GIS

Wednesday, April 22nd, 2015

The GRASS module i.topo.corr to correct topographic effects on imagery works quite impressively on the Landsat imagery using the recently released Enhanced Shuttle Land Elevation Data with a 1 arc / 30 meter spatial resolution. Here is a quick example to show the difference of the original image and the corrected image that was processed using i.topo.corr and the enhanced SRTM elevation model in GRASS GIS:
