Topographic Network of Madrid (RTM)

The City Council of Madrid maintains the municipal topographic network as a uniform and precise framework for the coordination of all topographic works and cartographic products that are carried out within the scope of the municipality. In 2020 it has been revised in its entirety and densified to cover new urban developments. From 2021 onwards it is updated annually. The Topographic Network of Madrid (RTM) consists of more than 5,000 vertices materialised in the field. It consists of vertices observed preferably by GPS and complementary by classical topography by precision polygonals. It comprises the entire municipality of Madrid, except in the Monte de El Pardo and the Castle of Viñuelas. It includes bumpers of the boundary line of the municipality, as well as vertices of other networks. It incorporates a subnet through all the tunnels of the city, so that it guarantees a single reference system both in surface and underground. It is supported by the national geodesic infrastructure through the network of GNSS reference stations (ERGNSS) and the High Accuracy Leveling Network. In the geoporta l of the City of Madrid is available the information and the complete services of this data set through the following link: Topographic Network of Madrid (RTM). You can consult geographically and download the vertices reviews in PDF format, as well as the full graph of vertices and visibility in SHP format or use the OGC.WMS and ESRI.REST services.
