Regular grid model of the emerged coastal strip, with a resolution of 50 cm, which expresses the orthometric altitudes of the terrain with the existing constructions in the territory (buildings, walls and other structures).

Orthophoto (mosaic of rectified aerial images) of the coastal strip (total or partial), with a resolution generally between 10 and 15 cm above the ground, generated from photogrammetric flights.

Regular grid model of 50 centimeters resolution, from all over Catalonia, which expresses the orthometric altitudes of the terrain, without the elements that may be above it (buildings, vegetation, etc.).

Topographic cartography covering part of Catalonia (urban areas, traces of roads, rivers, shorelines, etc.), compiled in 3 dimensions. Scale of reference: 1:1,000.

Orthophoto (mosaic of rectified aerial images) of the coastal strip (total or partial), with a resolution generally between 10 and 15 cm above the ground, generated from photogrammetric flights.

Regular grid model of the emerged coastal strip, with a resolution of 1 m, which indicates the orientation of the slope at each point of the terrain with respect to north.

Topographic cartography covering part of the territory of the Catalonia, compiled in 3 dimensions. It includes information related to the following layers of information: relief, hydrography, roads, and other transport networks; buildings, constructions and facilities; land covers, toponymy and municipal inventories. Scale of reference: 1:1 000.

Regular grid model of the emerged coastal strip, with a 1 meter resolution, which expresses the orthometric altitudes of the terrain, without the elements that may be above it (buildings, vegetation, etc.).

Orthophoto (mosaic of rectified aerial images) of the coastal strip (total or partial), with a resolution generally between 10 and 15 cm above the ground, generated from photogrammetric flights.

The orthophoto is a cartographic document that consists of a vertical aerial image which has been rectified in such a way that the same scale is kept in the entire surface of the image, being a geometric representation on scale of the terrestrial surface. It is a orthophoto with a resolution of 50 cm resolution generated by generalization from an orthophoto with more resolution, through pixel aggregation techniques. The infrared orthophoto (OI-5M) provides information about the infrared area of the electromagnetic spectrum. Shows the combination of IRC bands that correspond to Infrared, Red and Green channels, a combination called "false color".
