The boreholes database is an inventory of subsurface data in Catalonia through the collection of available geological and geotechnical survey information. The surveys are classified into three groups: surveys, penetrometers and trial pits.

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.).

Regular grid model of 1 meter resolution, from all over Catalonia, which expresses the orthometric altitudes of the surface of the territory, including the natural and artificial elements found on the ground (trees, buildings, etc.).

Mosaic of the territory of Catalonia representing the Normalized Difference Vegetation Index (NDVI), through the combination of rectified images captured by satellite in the red and near-infrared bands. This index allows estimating the vigor of the vegetation, based on the normalized difference between the radiation reflected in the infrared band of the electromagnetic spectrum with respect to the red band of the visible spectrum.

Names of the streets of the municipalities of Catalonia.

Regular grid model of 5 meters resolution, from all over Catalonia, which expresses the orthometric altitudes of the terrain, without the elements that may be above it (buildings, vegetation, etc.).

Regular grid model of 25 centimeters resolution, from the territory of the Barcelona metropolitan area, which expresses the orthometric altitudes of the terrain, without the elements that may be above it (buildings, vegetation, etc.).

Regular grid model of 2 meters resolution, from all over Catalonia, which expresses the orthometric altitudes of the terrain, without the elements that may be above it (buildings, vegetation, etc.).

Regular grid model of 1 meter resolution, from all over Catalonia, which expresses the orthometric altitudes of the surface of the territory, including the natural and artificial elements found on the ground (trees, buildings, etc.).
