Participation in national projects


Bardenas Reales

The Information System on Land Occupation in Spain (SIOSE) constitutes a very ambitious project that is framed within the National Plan for Land Observation in Spain (PNOT) that runs and coordinates the IGN/CNIG, with the aim of establishing a great geographic information infrastructure with multi-disciplinary use, updated periodically, available to the General State Administration and the participating Regional Administrations.

SIOSE aims to bring the precise data for integral knowledge of land occupation in Spain into a single information system. In this way, it contributes to the deployment of the INSPIRE European Directive.


CORINE Land Cover

CORINE Land Cover (CLC) is a project carried out with the following time frame references: 1990, 2000 and 2006 in Navarra. It attempts to create a European database that uses satellite images on a scale of 1:100,000 to establish the Land Cover and/or Use (land occupation).

The project is encompassed within the CORINE Programme (Coordination of Information on the Environment) that began on 27th June 1985 by virtue of a decision from the European Union Ministers Council (CE/338/85) and in 1995 it became the responsibility of the European Environment Agency (EEA).

Because European Union countries follow a series of community directives within this project, we now have perfectly comparable information for member states. The CORINE Land Cover project thereby became a fundamental tool for the environmental and statistics policy in the European field.


National remote sensing plan

The National Remote Sensing Plan (PNT) is an institutional cooperation project between organisations interested in observation data on the Earth. It aims to assure a systematic cover for the territory on different spatial and time scales with satellite images, financing its acquisition jointly between the General Administration and the Regions.

The PNT is currently working on three scales: high, based on merged SPOT-5 data (2.5 m), medium (Landsat-TM or equivalent, including historical cover) and low (MODIS, AVHRR, SEVIRI), which has not been incorporated yet.

The National Aerial Orthophoto Plan (PNOA) is a project that consists of obtaining orthophoto cover on a national level, based on common technical specifications, agreed by the different organisations involved.

It emerged as a joint project between the Regional Administrations and the General State Administration (AGE), boosted and coordinated by the National Geographical Institute. The project financing is shared by the AGE in each region, contributing 66% of the cost whilst the Autonomous Community assumes the remaining part.

This decentralised and cooperative production plan makes information capture more efficient, reduces costs and is framed perfectly within European Union trends such as the INSPIRE initiative advocating that geographic information should be compiled just once in maximum detail and shared openly among the different social agents that need it.

The development of this cartographic project consists basically of the following phases:

  1. Planning and completing photogrammetric flights.
  2. Calculating by means of aerotriangulation processes with topographical support.
  3. Obtaining the digital elevation model.
  4. Producing the orthophotography using orthorectification techniques.

CartoCiudad is the result of integrating and harmonising the data provided by different public organisations (General Cadastre Board, National Statistics Institute, Post Office, and National Geographical Institute) that has led to a road network database, census and postal information, covering the whole country.

In addition to a national street map, this project offers advanced geographic location functional features concerning any place in Spain through internet services
