KEY WORDS: geothematic data , geodatabase, GIS, 3D modeling. TITLE OF SECTION The importance of having a Continuous Territorial Geological lies in the possibility of being able to make it usable by the public authorities and professionals. Hence arises the need to correlate data collected for the obtaining of layers derived from the basic geology, geomorphologic maps, such as mineral resources. The purpose of this association was to create a data base on the spatial distribution of the subsoil in Tuscany due to the use of the same. Then highlight the protections, constraints, rules, problems and conflicts related to use of the subsoil and the possible impact on planning. The characteristics of Subsoil Use Atlas will be the ones to create a regional-scale consistency, with full compatibility with other regional database, to achieve high fidelity of the real situation and therefore be easy to update. The project phases include the retrieval of reference databases such as Geological Database (BDG), Quarries Mines Database (BDGM),Water Resources Database (BDSRI), Geological Surveys Database (BDIG), Thermal Mineral Water Database (BDCAMT) and Wells Geothermal Database (BDPGS). The next step consists in the creation of a new data structure derived from the intersection of information obtained from databases previously listed. The data derived from the operation of intersection allow to identify classes of criticality according to one classification proposed by the region of Tuscany in accordance with current regulations (Fig.1: Relationship of criticality). The formal description of the relationships between the entities in our possession and information related to them, belong to the main stages of conceptual design. The conceptual design is to analysis of scientific documentation relating to the domain specific

knowledge which is represented, in our case, from the layers of information and relative documentation connected to it. These documents provide a detailed description of the geometric characteristics and the entities that make up the database and have brought us a homogeneous layers of information design and the relationships between them. The first step was therefore the analysis of the documentation that has allowed us to achieve an integrated processing of geometries and attributes for setting up a new database. For the realisation of the new Database we made use of open source software like PostgreSQL with PostGIS (database server) for the management of the Data Base and QGIS for his view. The software open source PostgreSQL is an Object-relational DBMS that is a relational DBMS in which data is represented through tables and tables are managed using a high-level language called SQL Strucured Query Language acronym. This software has been joined by another open source software, PostGis, which provides geographic support. Through the use of SQL language, it was possible to realize a procedure (fig. 2: Database implementation workflow) that allows us to create and manage the new structure of Data Base (fig. 3: Excerpt of SQL procedure). 784

The final stage is the implementation of descriptive monographs of criticality, highlighting the causes, types, the impact on the resources concerned and finally formulating hypothesis. The descriptive monographs are structured in four parts. In the first section is the 2D representation of individual areas with critical legislation (Fig. 4: 2D and 3D Representation), follows the description of the layers of information, the next

part shows the analysis of regulatory detail. The next section shows the 3D reconstruction of the area containing the criticality with geological detail analysis and conclusions.
