Cadastral survey data structure

Cadastral surveying data is available in both graphic (on paper maps) and digital (computerised) form.
Digital cadastral surveying data is structured into eleven thematic layers which can be freely combined.

• Control points: points which provide the connection to the national geodetic coordinate system
• Land cover: buildings, roads, hydrology, forest, etc.
• Single objects: walls, wells, masts, bridges, etc.
• Heights: digital terrain model
• Local names: place names, locality names
• Ownership: land parcels
• Pipelines: high-pressure distribution network for oil and gas
• Territorial boundaries: municipal, district, canton and national boundaries
• Areas of permanent subsidence or landslips: areas which are subject to continual ground movement
• Building addresses: indications of geographical locations connected with buildings (road or street name, house number, postal code, locality name)
• Administrative subdivisions: sheet boundaries, instructions for labelling and lettering on the cadastral map, etc.
