Abstract

The importance and the limits of the study of thermal inertia using Landsat TM data for lithological discrimination are here described. A new algorithm was developed to compute thermal inertia using monotemporal data, by combining values of the absorbed radiance (co- albedo) with those of the emitted radiance (thermal band), considering also bandwidths and calibration coefficients of the TM sensor. this algorithm was tested on a 1024 X 1024 pixel Landsat TM image concerning an area located in southwestern Angola where different rock types outcrop.
