Geographic areas of settlement that appear in the Geographic Names Database of Catalonia (ICGC) and the Nomenclátor de municipios y entidades de población (INE), as well as clusters of buildings, and the polygons that appear in the Economic Activity Polygon Information System (SIPAE), with their names and codes and the administrative divisions where they are located. The interpretative delimitation of the settlement areas includes the representation and location of buildings and constructions with a defined urban structure and the groupings of buildings including the associated spaces that respond to the same geographical name.

Administrative units in which the health system of Catalonia is organized, in a deconcentrated way: health regions, health sectors and basic health areas.

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.

The Municipal map of Catalonia (MMC) is the geographic base with all the Municipal maps (MM) that have been considered by the Territorial Delimitation Commission (CDT) and that contains, for each map, the boundary markers, of the lines drawn and of the polygons resulting from the official municipal boundaries of the territory of Catalonia.

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).

Limits of the areas of natural interest defined in Decree 328/1992, which approves the Plan of areas of natural interest (PEIN), and any subsequent modifications that may have occurred. This base includes spaces at a scale of 1:50 000 and, in some cases, 1:5 000. The PEIN establishes a network of spaces representative of the rich landscape and biodiversity of the territory of Catalonia, from high mountains to coastal plains, and from Euro-Siberian forests to semi-desert wastelands or marine spaces. The PEIN is the higher level planning instrument that structures the system of protected areas of Catalonia and integrates this system within the whole territory, as it is a sectorial territorial plan framed within the Territorial Plan of Catalonia (1995). Subsequent to its approval, specific modifications to the rules and limits have been approved by decree, as well as extensions or additions of new spaces.

Set of tables that contain the information necessary to identify an address in a simplified way. This data is derived from the data base of municipal addresses of Catalonia.

Data set that contains the information necessary to identify an address (a concept that is expressed in a location and access route to a place where people can live and/or socio-economic activities can be carried out). Includes: town, street, portal number, postal code, road, kilometer point and building name. Covers urban areas and isolated buildings.

Geographical base that describes the subdivision of the municipalities of Catalonia into districts and census sections.

Geographical base at 1:5,000 scale which shows, for each of the municipal boundary lines, the status of the process of elaboration, approval and completion of each line of the municipal boundary for the execution of the Municipal Map of Catalonia (Decree 244/2007, of 6 November). The Municipal Map (MM) is the set of lines that make up the municipal boundary, regardless of the number of sections. The current municipal boundaries come from the replan made from the delimitation document of the early twentieth century, when they were first set. The project of the MM that are carrying out the Directorate General of Local Administration (DGAL) and the Cartographic and Geologic Institute of Catalonia (ICGC), facilitates to the city councils the procedure to modify the line of boundary and adapt it, if necessary, to the current reality of the territory, generating a new municipal line that once approved by the Plenary Sessions of the city councils and published in the DOGC remains as a line of current delimitation. The municipal delimitation is dynamic due to its link with the territorial changes, but today it is more so because it is subject to the evolution of the elaboration of the MM. The base is updated periodically based on the sessions of the Territorial Delimitation Commission, which take place three times a year.
