Abstract :
Fast and common forest cartography in the whole Spanish territory, based on the images provided by the AVHRR sensor, belonging to the NOAA satellites, can be of a great help to identify the areas where the most important changes of the forest covers have taken place. A non-supervised multitemporal classification based on six weekly composites images of the Normalized Differential Vegetation Index-NDVI-has been done. Its results are promising. The purpose is to obtain fast and inexpensive up-to-date cartography of the whole country
