Zone de Texte: A REVIEW ON GEOMATIC TOOLS FOR ASSESSING, INVENTORYING AND MAPPING ALIEN PLANT INVASIONS IN THE MEDITERRANEAN BASIN Zone de Texte: Data Collection Tools - Remote Sensing Zone de Texte: In the EU GeoRange project, spectral unmixing techniques based upon knowledge about the spectral response of relevant land surface materials in the Sardinian test sites were applied for the derivation of time-series (1985-2002) of vegetation change. Increase of (native) vegetation abundance (in the multitemporal fraction maps) is negatively correlated with the actual allodiversity. Zone de Texte: LC Classes removed from the analysis
