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.
