SITMUN is a platform that enables the creation and management of multiple geographic information applications (or SITMUN clients), both public and restricted access, from a single administration tool. The SITMUN administrator allows managing content, functionalities, and access permissions for each client application independently.

SITMUN clients are based on the SITNA API, developed by the Government of Navarra. The SITMUN platform arises from the collaboration between the entities that are part of the European SITMUN Network.
