Digital Land Model (DTM)

The Digital Land Model (DTM) is implemented in accordance with the standard defined in the Technical Requirements for the Production of Digital Terrain Models, produced by the appropriate working group named by the State-Regions-Local Entities agreement on Territorial Information Systems. The DTM complies with level 3. The DTM is geometrically integrated with all other regional topographic products, as it derives from the same aero-photogrammetric surveys of 2006 and uses the same models for orientation.
