    Representation, as a grid of 20 m resolution, of the following biophysical variables of the trees (the one identified in the Land Cover Map of Catalonia as wooded forest masses), which allow to know the structure of the wooded mass: Total aerial biomass; Total aerial carbon; Volume with bark; Foliar biomass; Basal area; Tree cover; Average normal diameter; Medium height; Foliar area index (available in some editions only); Density of feet per hectare (available only in some editions).

    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 250 cm obtained, by generalization techniques, from orthophotos with more resolution. Generally ortophotos of the serie Ortofoto of Catalonia 50 cm are used. The color orthophoto (OF-25M) provides information about the visible area of the electromagnetic spectrum. Shows the combination of RGB bands that correspond to the Red, Green and Blue channels, a combination called "natural color".

    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 color orthophoto (OF-25C) provides information about the visible area of the electromagnetic spectrum. Shows the combination of RGB bands that correspond to the Red, Green and Blue channels, a combination called "natural color".

    Orthoimage representing the normalized difference vegetation index (NDVI), with a resolution of 1 m. This index makes it possible to estimate the quantity, quality and development of 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. This set of information is distributed in 2 by-products: Real NDVI orthoimage, where each pixel takes the real value of the index in question (between -1 and 1), in such a way that it facilitates exhaustive studies but requires advanced software; 8-bit NDVI orthoimage, where each pixel takes the value of the index in question but discretized to an integer range between 0 and 200, so that it facilitates an overview.

    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 generated by generalization from an orthophoto with more resolution, through pixel aggregation techniques. The color orthophoto (OF-5M) provides information about the visible area of the electromagnetic spectrum. Shows the combination of RGB bands that correspond to the Red, Green and Blue channels, a combination called "natural color".

    The Territorial topographic referential constitutes the topographic base of reference with total coverage of the territory of Catalonia, and it includes information regarding relief, hydrography, roads and transport networks, buildings, constructions and facilities, land cover and geographical names. The elements are geometrically continuous (except in the case of too big polygons, due to the difficulty of their management within a GIS), the elements of the hydrographic network are connected and the road network is hierarchical.

    Topographic database that covers all the territory of Catalonia, compiled in 2.5 dimensions. It contains data relating to the relief, the hydrography, the transportation networks, the settlement and the auxiliary infrastructures, the toponymy, the reference points and a reduced set of land cover and vegetation classes. The reference scale is 1:25 000.
