Navarra Urban Information System (SIUN)

The Navarra Urban Information System (SIUN) is a project that began in 1997 in order to make it easier to access and disseminate all the approved, therefore also legally valid, urban information filed with the Government of Navarra. The system can locate and fully consult all the existing approved land development documentation at any point in Navarra. From its beginnings to the present day, Tracasa has been responsible for carrying out this project and, therefore, it has performed many tasks:

– Inventory and scanning of paper documents with land development information.

– Geo-referencing cartographic documentation.

– Definition of the data model.

– Digitalisation of the urban information and development of editing tools.

– Development of the SIUN Web portal and publication of all land development information.
