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

Geographic base of the decentralized municipal entities (EMD) of Catalonia, with their names and codes, derived from the delimitation files of the entities and the municipalities to which they belong, and from reference cartographic sources. Of the boundaries of the polygons of the EMD represented in this base, only those that have a recognition act, a resolution published in the DOGC or a judicial resolution that determines the current official line are definitive, as long as they have coordinates in the current reference system. The rest of the boundaries must be considered provisional. The EMD are a type of entity with a territorial scope lower than the municipality, that is, local governments below the municipalities.
