SITMUN (Municipal Territorial Information System) is a collaborative platform to develop multitenant municipal territorial information systems. It is designed to be deployed in territorial entities larger than a municipality (typically administrative units sized between NUTS 3 and LAU1) in order to provide their SDIs with GIS tools, applications and services to serve the municipalities belonging to their territories in a cost-efficient way.

SITMUN started in 2003 in an INTERREG IIIB SUDOE project promoted by seven provinces, councils and public organisms from Spain and Portugal. In 2005 the SITMUN European Network ( was created to continue this project. The current version of the system was developed in 2010-2011 driven by the cooperation of five Spanish public administrations. It is modular and makes a special emphasis in using and providing SDI and INSPIRE data and services. It is currently used by 8 territorial entities (Consell Insular d’Eivissa, Consell Insular de Mallorca, Consell Insular de Menorca, Consorci de Tecnologies de la Informació i de les Comunicacions de Mallorca, Diputació de Barcelona, Diputació de Girona, Diputació de Lleida and Diputació de Tarragona), covering up to 1,000 municipalities, and has 3,000 registered users.

The current version of SITMUN has been deployed and maintained for almost 8 years, and it was increasingly difficult to maintain, fix and improve. The development of a new version of SITMUN started in 2017 to address these problems. The objective is to take the experience of the previous system, and apply it to a new system, developed from scratch with the following main characteristics: -Open source and open development on GitHub -Customizable applications with functionality based on plug-ins. -Common applications that require a minimal customization (e.g. Urban Planning), but also the possibility to develop specialized ones. -An architecture following well-established standards and technologies, with a Java stack in the back-end supported by the Spring framework and access to different databases. Different choices for the front-end are still being evaluated. -Best practices for development and deployment: dependency management with Gradle, automatic builds on Travis-CI, static code analysis on SonarCloud, etc. -Responsive, modern web applications that support common devices. -Closely connected to standards, SDIs and INSPIRE datasets and services.

SITMUN welcomes any kind of collaboration, from usability and functionality suggestions to organizations interested in testing and deploying in their own territories, contributing to the code development or even becoming partners of the SITMUN network.
