    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 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.
