Zone de Texte: A REVIEW ON GEOMATIC TOOLS FOR ASSESSING, INVENTORYING AND MAPPING ALIEN PLANT INVASIONS IN THE MEDITERRANEAN BASIN Zone de Texte: MetaData – “Information on Information Resources” Zone de Texte: The resulting increasingly use of geomatics, from one hand, have given new insights into phytogeography and plant invasions processes, reviving scientific fields that are often reach in theoretical concepts, but from the other fuelled the need for international standard for metadata definitions, data quality and for comparing, updating, exchanging and retrieving data, maps and experimental results. The problem of comparing studies on single species or whole exotic floras between countries has been, so far, mainly addressed toward its main focal point, that is taxonomic and terminological coherence, yet many other topics need to be addresses, especially when data are provided by mean of geomatic tools or presented in digital format and maps.
