Metodologia GIS per il rilevamento dei Geositi

We would like to propose a new methodological approach that can be used in different geological and geomorphological contests to analyze Geosytes through the realization of vectorial maps and the construction of relational database. General finalities of the project are to represent the territory in all its different aspects in a way the most possible close to reality. Landscape analisys happens through a process of census and integration among elements that characterize it enhancing scientific and environmental meanings with use of a particolar form produced by ISPRA turning it into a relational database connected with a specific GIS cartography. This standardized methodology is based on Minimal Land Unit, that define in a unique way the Geosiyte with its areal charateristics, as units of 1 Km2. With use of a square grid every goods can be placed in one or more square of the grid. Every Geosyte can be identify both spatially through the square Km where it is and in its descriptive features through the relational database associated. Area analysys could be deepen with some thematic maps, and especially land use with Biohab, a methodology for survey, survellance and monitoring of habitats that is standardized at European level, based on the classification of Raunkiaer plant life form. Really important is the use of a global georeferencing system, WGS84, integrated with UTM, a projected system that allow areal elaborations too. Geosyte study is completed by tridimensional elaborations and marking out some paths based on precises travelling times with use of particular Arcgis tools, always taking into account interoperability concept and an easy access for geoturistic purpose through an interaction with open source site as Google Earth, Arcgis Explorer and use of Qrcode. Finally there is a valutation of some specify study case that allow the application of this methods in heterogeneous situations, as Temporal Geosytes, marine areas and archeological areas.
