Traitement d'images et analyse de surface d'onde liées à l'observation terrestre et spatiale.

Abstract

The aim of this work is to develop a physical model interpreted by program. Three kinds of data were analyzed: LANDSAT7 TM, ETM+ and ALSAT 1. After the geometric correction on the satellite image, and selection of the interested area, we have analyzed the spectral signatures of the classes which gave us an idea of their homogeneity and heterogeneity. We have carried out unsupervised and supervised classifications. And finally, we have used the normalized difference vegetation index (NDVI).
