Abstract :
Optical and microwave remote sensing data, from the northeastern of Portugal, was used to the discrimination of lithologies outcropping in that region. Classification techniques was applied and from the results it can be concluded that the optical data performed a better discrimination that the radar data. In this last case, a texture analysis shows that the mean (with matrix of 5*5) gave the best results.
