Résumé:	Three SPOT HRV (Land Observation System) satelite images were taken with a multispectral sensor (XS) in three bands: yellow-green (0.50-0.59 nm), red (0.615-0.680 nm), and near infrared (0.79-0.89 nm), with a 20 x 20 m resolution, equivalent to 12 pixels (picture elements). These data were used to define check plots that were analyzed based on SPOT images corresponding to March and September land use classification into broad categories continued using the reflectance classification established at the field level. To identify cultivated and native pastures by botanical composition and degree of degradation, information covering several periods of the same year is needed, with at least one record made during the dry season and another during the rainy season. If only one is feasible, the information corresponding to the end of the rainy season is most appropriate, especially if many burnt areas exist. Data from the dry season, however, are more indicated when studying degraded areas.
