Toponyms (place names) present in the cartography of the Cartographic and Geological Institute of Catalonia, such as the names of municipalities and heads of municipalities, population centres and isolated buildings, facilities and equipment, relief elements (oronyms), hydrographic network and point hydrography (hydronyms), protected areas and other unique elements of the territory; with the coordinates of the point where they are located.

Reference topographic geoinformation with total or partial coverage of municipal management areas or geographic areas of specific themes that require detailed topographic information. It includes information related to the following layers: relief, hydrography, road network and other transport networks; buildings, constructions and facilities; land cover, toponymy and municipal inventories. This geoinformation can have different levels of resolution, corresponding to scales between 1:500 and 1:2000, although the most widely used is 1:1000. The data distribution includes an additional address layer (derived from the Catalonia address database at the time of creation or revision of the Local topographic reference of each municipality).

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.
