Implementation and Management Approach
Geoportal MITYC  is a collaborative project between different administrations (IGN, D.G.CATASTRO, MITYC) and enterprises of the energy sector (operators in gas stations businesses, Repsol, Cepsa,BP, etc.). These operators send information each week and every time they change prices using a web form or by sending an SMS. The application receives the information and refreshes these prices online in order to get the most recent information about prices and public opening hours of gas stations. This information is shown on a GIS system that combines alphanumeric information with maps, where users can see the location of each gas station. It has a gateway with Google Earth in order to  be updated regarding routes and distances, also present in versions for mobile phones, PDA´s, GPS navigators and TDTi.
The version for mobile phones combines the possibility of seeking in an alphanumeric way by region, address or postal code for each kind of fuel; or looking this information over the maps and photos provided by the National Geographic Institute of Spain using Geoportal Tools.

Technology solution
Based on WMS (Web Map Services), it uses Open Source software (Maps Server) to publish the maps, and AJAX (Asynchronous Javascript and Xml) to provide this information to  all users consulting the system.  The project for multi-channel access (mobile phone, PDA´s, GPS navigators) uses java and xml and some libraries' open source in order to provide information.
Version for GPS navigators allows drivers with these gadgets to get daily the file including the location and prices of gas stations in the format used by their navigator(for example Tom Tom users can get an .ov2 file in order to copy it in their Iberia maps folder to obtain this information while there are driving).
TDTi version is based on a Java framework and uses MHP (Multi Home Platform) standard to provide interactive services on TDT (terrestrial Digital Television) channels with interesting information managed by Public Administrations.
The project is based on the ideas of the web 2.0 trying to provide users attractive information. There are several mashup services using information provided by the MITYC to get economic benefits with this information (for example people who draft gas maps).
