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.

Synthesis of the hydrogeological macrounits into which the territory can be divided, called hydrogeological areas, and classification of the formations of the Geological Map of Catalonia 1:250,000 according to their lithological characteristics, type of porosity and consolidation.

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).

Classification of soil according to its agrological capacity (ability to sustainably produce the most common crops in an area), in one of the 8 classes established by the Generalitat de Catalunya (Government of Catalonia).

Delimitation, location and attributes of the elements of geological interest identified in Catalonia that are included in the Inventory of Areas of Geological Interest of Catalonia published in 2000 and updated in 2020 and of those that have been identified in other inventories or scientific and informative publications. Spaces of geological interest are places of interest for their unique and/or representative nature, which allow the study and interpretation of the origin and evolution of geological domains, including the processes that have shaped them, the climates of the past and its paleobiological evolution; and constitute the geological heritage of a territory.
