swissTLM3D
swissTLM3D is the large-scale topographical landscape model of Switzerland. It includes both natural and artificial landscape features, as well as name data in vector form. With a high accuracy and the incorporation of a third dimension, swissTLM3D is the most extensive and accurate 3D vector data set of Switzerland.
Version 1.1
swissTLM3D is available for all of Switzerland and the Principality of Liechtenstein. The current release has the version name swissTLM3D 1.1. A PDF document containing a full overview of the swissTLM3D 1.1 data catalog including a list of modifications made in comparison to swissTLM3D 1.0 is available on this site.
For additional update versions, see The Topographic Landscape Model TLM.
Structure
swissTLM3D describes around 10 million landscape features, complete with their position and shape, the corresponding landscape feature type and many other attributes.
| Topic | Description |
|---|---|
| Roads and Tracks | Road and path network, cycling paths and footpaths |
| Public Transportation | Railway tracks and other rail systems, shipping routes and public transport stops |
| Buildings | Buildings, walls, dams, constructions relating to transport, communication, energy, sport and leisure |
| Areas | Plots with special land usage (transport, habitat, industry etc.) |
| Land cover | Ground coverage independent from land usage |
| Hydrography | Watercourses and lake contours |
| Single Point Objects | Selection of prominent landscape features which aid orientation (crossings, sources, caves) |
| Names | Various names (mountains, areas, towns) |
File formats:
swissTLM3D is available in the following file formats:
- ESRI Personal Geodatabase
- ESRI Shapefile (3D)
- DXF
- Interlis 1 / Interlis 2 (on request to geodata@swisstopo.ch)
Coordinate system:
swissTLM3D is available in the following Swiss coordinate systems:
- LV03 LN02
- LV95 LN02
Quality
Geometric accuracy: from VECTOR25 (3 - 8 m) through to swissTLM3D (0.2 -1.5 m in all three dimensions for well-defined landscape features such as roads and buildings, 1 - 3 m in all three dimensions for landscape features which are not clearly defined such as forests)
Applications
swissTLM3D can be used for a wide range of applications thanks to its simple and clearly defined landscape feature structure:
- as a reference data set for establishing information systems (e.g. dynamic segmentation based on the road network of swissTLM3D)
- as a basis for 3D visualisations and analyses (depending on the application, in conjunction with swissALTI3D)
- as a data basis for simulations, plans and statistics
- as a starting point for publications (maps, plans, Internet) and finished products (e.g. multimedia, navigation or geomarketing CDs)
