The interface is in Croatian and English. The positive aspect of containing information on more than one RES is negatively counterbalanced by the lack of information on the availability of the resources. Data and location has been extracted by the register containing basic information on all RESs plants (planned, meaning those that are in the process of acquiring the status of preferential producer, or working). projects also including planned plants and installations. The overall goal of this application is to give an overview summary of all the projects.

Few GIS applications have been created dealing with geothermal energy sources. Examples at the national level regard Italy, Slovenia and Romania.

The GeoThopica project uses data from Italy that has been gathered from existing databases and maps dealing directly or indirectly with geothermal resources. These specifically are: (1) the inventory of the Italian Geothermal Resources (1986), (2) “Groundwater – Inventory of data collected by AGIP during the research on hydrocarbons in Italy between 1971 and 1990”, (3) “Underground temperatures – Inventory of data collected by AGIP during the research and the production of hydrocarbons in Italy – 1977”, (4) “Update of underground temperatures – Ground wells – December 1986, AGIP”, (5) data published from the Ministry of Economic Development (UNMIG) and (6) Hydrogeological compounds of Italy – from the Atlas of water resources of the European Community (J. Mouton et al.).

The created database, supported by GIS, contains (1) the surface stratigraphic data, (2) the characteristics of hot springs, gas and events with relevant data of geothermal wells, (3) the isotherms at 1000, 2000 and 3000 m from ground level, (4) the heat flow to the surface and (5) the positions of aquifers. In Figure 2 an example of the WebGIS view is given.
