The INTERLIS Compiler checks an INTERLIS model (INTERLIS 1 and 2) if the constructs of the language INTERLIS were applied correctly. It reports syntactic errors in the model with the line number so that they can be corrected by the modeler.

Software errors of the INTERLIS Compiler or new tool requirements can be registered directly on the developer platform GitHub.


INTERLIS is a conceptual modeling 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 swisstopo (COGIS)
