Zone de Texte: A REVIEW ON GEOMATIC TOOLS FOR ASSESSING, INVENTORYING AND MAPPING ALIEN PLANT INVASIONS IN THE MEDITERRANEAN BASIN Zone de Texte: In this concern and debate, geomatic tools, i.e. informatics’ tools and methods applied to geography and geo-sciences, such as e.g. GIS, tGIS (temporal GIS) and web-GIS, GPSs, data-bases and remote sensing, are becoming widespreadly used for basic research on IAS, for assessing, inventorying and mapping allodiversity from genes to species, for data transfer, sharing and comparison, for landscape-scale or spatial analysis and geostatistical studies, retrospective analyses or early detection and management purposes. The reducing costs, the increasing know-how inside the scientific community, public administration, stakeholders, the pressing need to exchange data in quantity and time between different parts of the world, to address the global vegetation change processes, are fuelling the spread of the use of geomatics in the research and management sector.
