It is interesting to look back at a few initiatives that, whilst we are not able to consider them as forerunners to SITNA, still highlight Navarra's historical interest in knowledge on the territory and geographic issues:
Much more recently we find some sector-based developments that have been carried out by different units of the Provincial Administration that might be considered as the true ancestors of SITNA:
In 1966 the Navarra Cartographic Plan began. In addition to its specific results, its work provided unique geographic references for all data that can be geo-referenced. The different Catalogues and particularly the catalogue published in 1999, have been decisive contributions to SITNA's design.
In 1974 the first steps were taken towards modernising the Cadastres and in the following decade the Urban and Rustic Cadastres were implanted. From the Territorial Wealth Service Board proposals and fertile dynamics have emerged for the birth of SITNA.
This Department integrates two highly interesting initiatives: The Navarra Environmental Information System (SIAN), working since 1991 and the more recent Navarra Agrarian Territorial Platform (PLANTA). Both projects have been working on preparing and managing layers of topic-based information of interest for their different administration and management tasks.
As the result of their joint work with the Territorial Wealth Service and TRACASA, in 1996 the Navarra Statistics Institute carried out the "Navarra Population Statistics", the first statistical georeferenced census operation in Spain. This operation represents the starting point for bilateral procedures processing geographic information, which lies in the origins of SITNA.
Since 1997 this unit has been developing the Navarra Town Planning Information System (SIUN) in order to approach the information society relating to instruments of ordinance and planning in force in Navarra.
