Impact
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).
Track record of sharing
GEOPORTAL MITYC is the most visited page among those generated by the said Ministry. Â Last year more than 2 million people visited the portal to get information in more than 40.000.000 pages.
 There are several mashup services (gassmappers, gasolinaeeconomica.com, elpreciodelagasolina.com...) using the MITYC information in order to make profit of it what shows how useful it is.
More than 20 articles in one year in newspapers in Spain (including national, regional and local newspapers) and several references in the most important blos in Spain (microsiervos,blogIDEE,...) show their relevance.
This project was selected as an exemple of best practices in TSDI (Tematic Spatial Data Infrastructure) and presented in Lisbon 2009 eSDInet+  Workshop.
This case was selected as a case of success in the SITI ASLAN Forum in March 2009 as an example of public sector multi-channel delivery solution.Â

Lessons learnt
All Collaborative projects within public sector and initiatives based on open source software need less money to invest and the results show that SDI based on collaborative networking are now the best option in order to develop GIS projects.

Public Administrations manage a lot of useful information for citizens. Taking into account citizen needs can be the firs step into a successful case. With the new vision of Web 2.0 Public Administrations will notice that they should look for interoperable systems, using collaborative tools and standards to allow interactive services with citizens and enterprises.
This new point of view will change the public administration portals to provide more useful and accessible pages for citizens, because they are demanding this kind of services.
