Urban Geology': Documentation of geo-thematic information for urban areas in Greece, the case of Nafplio Greece

摘要

The Institute of geological and Mineral Exploration of Greece (I.G.M.E.), in the frame of CSF 2000-2006 (Community Support Framework 2000-2006), has been implementing the pilot project titled "Collection, Codification and Documentation of geothematic information for urban and suburban areas in Greece - pilot applications". Geological, geochemical, geophysical, geotechnical, hydrogeological and other data concerning the urban and surrounding areas of Drama (North Greece), Nafplio & Sparti (Peloponnesus) and Thrakomakedones (Attica) is collected. Drillings, geological and geotectonic mapping (scale 1:5.000) and other "in situ" measurements and field works are taking place. The contours of the 1:5.000 topographic maps are digitized and a high detail DEM is created. The DEM and ground control points collected with GPS are used for the Orthorectification of very high-resolution satellite data. Then, the orthorectified satellite data is used for the land use classification and the urban area mapping. All initial and derived analogical and digital data is compiled and processed in specially designed geo-databases in GIS Environment. The final results will be presented in geothematic maps of different scales (1:5.000, 1:10.000 etc). Thematic maps (geological, geotechnical, geochemical, geophysical etc) and other digital data such as geodatabases, DEMs will be available to all, public or private sector, concerning geological environment in urban and suburban areas. All these data will constitute the essential base for land use planning and environmental protection in specific urban areas. Through this pilot project, new scientific approaches, methodologies and standards will be developed and improved in order to be applied to other future projects concerning capital centers of the country.
