Continuous digital hydrogeological cartography 1:25,000 is a set of geothematic information related to the quantitative and qualitative characteristics of groundwater, the environment that contains it and the associated hydrogeological elements such as wells, piezometers, springs and water mines.

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 central element is the 1:25,000 geological map; the rest are called peripheral elements. The peripheral elements are: the legend of the cartographic units, the conventional signs, the stratigraphic columns, the geological sections, the stratigraphic relationship diagram, the geological diagram and the complementary diagrams. The geological map shows the distribution of different types of rocks that emerge on the surface of the earth and their relative arrangement. It allows us to deduce much of the arrangement of rocks in the subsoil and to learn about the geological history of a region. It is a two-dimensional graphic representation that allows us to make extrapolations in three dimensions or, even, four if time is considered, depending on the level of reading that is made. It is formed by a set of cartographic units limited by contacts and by symbols that represent other geological elements: surface dip, folding structures, subsoil information (isopachs or isobaths of the Quaternary), slope of recent deposits, morphological indications, landslides and other recent processes, deposits, etc. It also includes symbols of various references (geological sections, drillings, names of major geological structures, etc.).

This geoinformation is a cartographic document that provides a global view of the country's soil structure and offers, in a synthetic form, information on the distribution of soils in the territory, their morphologies, and their physical, chemical and biological characteristics.

Soil information on soil profiles described in the field, with varying degrees of detail, both of the place where the observation is made and of the profile described. Including its composition in horizons, morphological description and physical-chemical characterization, such as the type of soil.

Basic hydrogeochemical data of groundwater analyzed in various locations in Catalonia (sources, springs, wells...).

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.

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.

Magnetic anomaly measurements and zoning of the territory according to this at a scale of 1:250,000.

1D/2D geophysical data, obtained through the application of different geophysical methods in different locations in Catalonia, consisting of the measurement of different physical parameters of the subsoil to obtain information on the behavior of its materials and its structure throughout the territory. Specifically, this set of information includes data, profiles and models resulting from the application of the following geophysical techniques: Magnetotelluric (MT); Electrical Tomography (ERT); Vertical electric sounding (SEV); Seismic refraction Survey (SRA); Seismic reflection survey (SRX); Surface wave analysis (MASW); H/V spectral quotient; Passive seismic array (ARRAY); Geophysical testing in wells.
