The Geological Survey of Italy in order to make available relating to geological data and maps, in the geoportal SGI has built a series of tools that allow access to all information stores of several databases, developed inside, and meet different users. The SGI has realised a first version of Geoviewer with flex technologies (flash builder) which was presented within the Geoportal SGI during the 2010, has also developed an evolution of the same viewer. The new version of the viewer is due to two reasons: from technological point of view in order to make available a more friendly interface to the user that has more tools like analysis widgets; from the other point view to re-organise the contents of data based on the great feedback received over time by the uses. In particular the new geoviewer is structured in three thematic sections related to the geological content: the geological data where is stored all the data that represent map distribution of the geological data or the data that have generic content. The second theme is represented by the Geologic resources like prospection, boreholes or quarry and the third theme is represented by the hazard events, like landslide, active faults, sinkholes, etc. To support the data is realised a set of tools to query and analyze the data: for each layer discoverable in each web service has been developed a specific query window and for some data is possible to operate a combo advanced query to highly the geologic results. Otherwise to easily manage the extra external data an "Add Widget" to manage the web service in several standard (WMS, KML, ArcGIS Server, ArcIMS, Image) has been developed. Moreover in the viewer the major base maps has been integrated and now are available OpenStreetMap, Google Map, the Environmental Ministry Ortho-images together at the previous Esri and Geological Survey of Italy base maps.
