Abstract

A comparison of topographic correction methods is conducted for Landsat-5 TM, Landsat-7 ETM+, and SPOT-5 imagery from different geographic areas and seasons. Three successful and known methods are compared: the semi-empirical C correction, the Gamma correction depending on the incidence and exitance angles, and a modified Minnaert approach. In the majority of cases the modified Minnaert approach performed best, but no method is superior in all cases.
Keywords: topography; C; Gamma; and modified Minnaert methods; multi-sensor imagery topography; C; Gamma; and modified Minnaert methods; multi-sensor imagery
