The project is based on a strongly technological Â and innovative structure, and exploits the new Information and Communication Technologies in order to increase the diffusion of an enlarged geographic knowledge among all citizens. Besides constituting a medium for geographic knowledge diffusion, it has also offers practical useful services, that can be used both by citizens and companies for personal and business purposes. SeveralÂ freely web-accessible navigators have been developed, both very user-friendly and more professionals-dedicated, which allow to use the geographic information granted by an official government, as the Regional Public Administration is, in a easy and catchy way.
The diffusion of the web-based free geographic information directly implements those principles of innovation as the motor for economic change, of "learning economy" and finally also of "Social and environmental renewal", designed by the Lisbon Strategy.
Free and widespread accessibility to geographic information is also hoped by INSPIRE Directive (2007/2/EC), which states that the spatial information plays a key role in improving the territorial government, monitoring the environment, and therefore improves the citizens quality level. The project strongly implements the operational guidelines delivered by the INSPIRE project (in its Implementing Rules and in the Commission Regulation (EC) No 1205/2008 of 3 December 2008 implementing Directive 2007/2/EC of the European Parliament and of the Councilwith Â regards to metadata), therefore giving the basis for a solid and effective spatial data infrastructure. The project is therefore quite well embedded in the European context on geographical information, and also at a national level it constitutes nowadays one of the best practices, due to its completeness and to the newness of the technologies used.
Actually, the Italian National Authority of Informatics in Public Administration has recently delivered Draft Technical Guidelines for the creation of a National Register of Spatial Data, constituting the annex to a Draft Decree of the President of the Minister Council, which will be probably become definitive in few months.
SITR-IDT has already almost totally implemented these guidelines, which mostly concern metadata on spatial data.
Planning of the territory is one of the primary purposes that the SITR-IDT system has fulfilled, by giving services and information supports to allow local public administration to improve the planning of their territories respecting the environment and the landscape.
E-government finalized services and applications have been created, that will be made available to Sardinian local public administrations to improve their management of bureaucracy for the control and monitoring of the territory, in order to grant its protection, valorization and enhancement. In the project, a very important section is dedicated to the management of cadastrial data by information media. Implementing the Italian national law concerning the standardization and the management at a unique national level of all the tributes and fees correlated to cadastral information, a dedicated service has been created. It consists of services of download of the official cadastral data at the most updated level, according to the national project called "Sigmater"; besides, SITR-IDT has developed specifically dedicated software, with the functionalities of the modern GIS software, which allow the management of all official territorial data, exposed by the SITR-IDT services, together with cadastral data.
