The Topographic Landscape Model TLM
The topographic landscape model is the central instrument for the production of national geodata. It contains objects that shape the landscape, e.g. buildings, roads and bodies of water. These data are recorded, processed, managed and kept up to date by swisstopo, with a high degree of accuracy and in three-dimensional form, and are subsequently placed at the disposal of the various users. The topographic landscape model forms the basis not only for the production of the national maps, but also for a broad range of spatially-related applications.
