swissBOUNDARIES3D

swissBOUNDARIES3D contains all administrative units and national boundaries of Switzerland and the Principality of Liechtenstein in vector form. It is based on an optimised data model for Switzerland and conforms to the data of the Swiss Federal Statistical Office.

Administrative units of Switzerland

Update July 2021: two new political municipalities
The latest edition of swissBOUNDARIES3D contains two new municipalities created through fusions of eight old municipalities.

  • Canton of Vaud: Assens, Hautemorges

Applications

Thanks to its simple and clearly defined data structure, swissBOUNDARIES3D can be used for a broad variety of tasks:

  • Analyses requiring a spatial reference to the administrative divisions of Switzerland
  • Use in combination with other geographic data sets
  • Visual background for orientation in GIS, CAD and navigation systems
  • Wide-area statistical analyses and simulations
  • Reference data set for the development of information systems

Technical Details

Structure

swissBOUNDARIES3D comprises  5 information layers:

  • Administrative boundaries (national, cantonal, district and municipal boundaries), line geometry
  • Administrative base units (e.g. municipalities), surface geometry (polygons)
  • Districts, surface geometry (polygons)
  • Cantons, surface geometry (polygons)
  • National territories, surface geometry (polygons)
     

To produce the third dimension, the administrative boundaries were projected on to the digital elevation model swissALTI3D. The lines and contours are therefore geometrically specified as three-dimensional points (x, y, z).

The swissBOUNDARIES3D perimeter includes Switzerland, the Principality of Liechtenstein and the exclaves in neighbouring countries. In addition to political municipalities, areas such as the State Forest of Galm, lakes and other common areas larger than 5 km2 which are not assigned to a specific municipality are also designated as independent surfaces.

File formats

swissBOUNDARIES3D is available in the following data formats:

  • ESRI File Geodatabase
  • ESRI Shapefile (3D)
  • DXF
  • Interlis 1 / Interlis 2

Coordinate systems

swissBOUNDARIES3D is available in the existing Swiss coordinate systems:

  • LV03 LN02
  • LV95 LN02

Updating

swissBOUNDARIES3D is updated annually. Updating is based on information provided by the Cadastral Survey (CS) and the Federal Statistical Office.

Geometric enhancement

The generalised data of GG25 at the 1:25,000 scale were imported into swissBOUNDARIES3D.The geometry of the data set is being continually improved through the integration of Cadastral Survey data, which are derived from the surveying and measurement processes for national borders. The progress of these processes is published in each information update.

Quality

  • Full national coverage in homogenous form and quality 
  • Horizontal accuracy: 0.5 m areas with improved geometry, 3-8 m in the other areas 
  • Vertical accuracy: 0.5 m in areas below 2000 m, 3-8 m the other areas 
  • Stable and unambiguous object identification 
  • Simple structure
