Potentialités de l’imagerie satellitaire Spot 5 pour la cartographie de la végétation terrestre

The aim of this study is to test the Spot 5 satellite imagery for the cartography of terrestrial vegetation in the prospect of a monitoring of coastal zones. Two methods are used. The first method is based on a photointerpretation of a 2.5 meters multipectral image with the european EUNIS habitat cl...
