Data models
The INTERLIS geodata description language enables the modeling and integration of geodata and thus facilitates data exchange between different geoinformation systems. INTERLIS can be used independently of the software and IT system used. INTERLIS has been the official standard for data exchange within the official cadastral survey (AV) since 1998.
INTERLIS is also suitable for the exchange and documentation of geodata in other areas such as spatial planning and line cadastre. In Liechtenstein, both the data of the official cadastral survey and other data of the Liechtenstein geodata infrastructure (GDI), such as zone plans and line cadastre, are described in the INTERLIS format.
All data from Liechtenstein's geodata infrastructure can therefore be exchanged between different IT systems via INTERLIS.
Further technical information on Interlis can be found on the Interlis platform. Information on the use of Interlis in official cadastral surveying can be found on the Internet portal of the Swiss Official Cadastral Survey.
