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.

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.

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 25 cm generated from images with a pixel resolution variable according to the zones. The infrared orthophoto (OI-25C) 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".

The metropolitan topobathymetric elevation model is a representation of the surface of the coastal strip, both the emerged part (dry beach) and the submerged part, up to an approximate depth of between 15 and 20 meters. The depth is represented with a regular grid of 1 meter pixel size. The emerged part is measured with topography methods, the first meters of the submerged part are measured with a single-beam echosounder and the rest is measured with a multi-beam echosounder, which provides very detailed data of the seabed.
