Delimitation of the hidrogeological units of Catalonia (aquifers, aquitards, aquicludes and aquifer systems), i.e. those parts of the lithosphere with distinctive parameters for water storage and conduction. The data model of this geoinformation is based on the technical specifications of geological data of the INSPIRE Directive (2007/2/CE).

Synthesis of the geological constitution of Catalonia through the cartographic representation of lithostratigraphic geological units, major structural elements (unconformities, faults and folds) and types of contact between units. The situation of the soundings carried out for the exploration of hydrocarbons is also included.

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.
