Information levels & data
Digital cadastral surveying data are divided into eleven thematic levels that can be freely combined with one another.
The eleven information levels
Cadastral surveying data are available in analogue or digital form. Digital data are divided into eleven thematic levels, which can be combined with one another as desired.
- Fixed points: points that provide the reference to the coordinates system
- Ground cover: buildings, roads, bodies of water, forest, etc.
- Single objects: walls, fountains, masts, bridges, etc.
- Heights: digital terrain models
- Nomenclature: field and place names
- Real estate: plots of land
- Pipelines: high-pressure gas and oil pipelines
- Administrative boundaries: municipal, district, cantonal and national borders
- Permanent ground movements: defined regions that are permanently in movement
- Addresses of buildings: designation of geographic locations relating to buildings (street name, house number, postcode, name of town/city)
- Administrative sub-divisions: map boundaries, details for designation of plan for the land register, etc.
Digital data can also be linked to and combined with other spatial data, e.g. noise register or zoning plan data. Data can also be exchanged between different geographic information systems thanks to a specially developed geodata description language called INTERLIS.
