Kartenausschnitt

INTERLIS is a description language designed to ensure long-term compatibility between different systems. INTERLIS is software and system independent.

The most currently used version is INTERLIS 2, version 2.3.

INTERLIS - who is behind it?

COGIS (Coordination, Geo-Information and Services) is the guardian of the formal language INTERLIS and provides the necessary information and documents. The activities of the Federal Administration in the field of geoinformation (GI) and geoinformation systems (GIS) are also coordinated by COGIS. See https://www.kogis.ch
