چکیده

Nowaday, the localisation of vegetation using satellite images is a classical application of remote sensing. More precisely, using very high spatial resolution images (such as IKONOS, Quickbird or Spot Vegetation) allow to accuratly localise forest border. This allow for example to follow the evolution of forest surface in order to prevent deforestation. But to correctly survey biodiversity we have to split forest into more precise area regrouping same kind of vegetation and environment (height, humidity, ground, ...). This is all the more so important if the resources are dispersed and fragile. Most Caribean Island are in this case and biodiversity has to be carrefully supervised. In this paper we propose a way to iteratively re ne the localisation of the di erent kinds of forest by using a fusion between satellite images information and geographical information.
