Abstract

Due to the failure of Landstat 7 ETM+, Landstat 5 images are widely used in many fields again since May 2003. In this letter, a method, based MODTRAN+TM+topographical maps, was used to solve the preprocessing problems of TM images towards retrieving of the endmembers. It proved effective to retrieve the reflectance values of surface substances and confirm the pure surface endmembers before an in-site spectral experiment. The result was also consistent with actual reflectance of surface substances. A case of retrieving endmembers in Luancheng, China was too demonstrated
