Official surveying interface
The cadastral surveying data model is described in the standardized and system-neutral data description language INTERLIS.
The data can also be output at any time in the standardized INTERLIS transfer format and read in again by any IT system that is capable of interpreting INTERLIS. The data description in INTERLIS and the transfer format derived from it together form the Official Surveying Interface (AVS).
By using the standardized and system-neutral AVS, system independence is achieved in data management, which guarantees the long-term use of cadastral surveying data that extends beyond the service life of software systems.
The Liechtenstein data model is compatible with the Swiss basic data model and adapted as far as possible to that of the eastern Swiss cantons.
The Interlis description of the Liechtenstein cadastral surveying data model and further information can be obtained from the Office of Civil Engineering and Geoinformation, Surveying and Geoinformation Division, or downloaded directly from the Guidelines and Documents section.
