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 geology of Catalonia at a scale of 1:50,000 through the cartographic representation of geological units of a lithostratigraphic nature, of the major structural elements (unconformities, faults and folds) and of the types of contact between units.
