INTERLIS in QGIS - The swiss approach of model driven data harmonization
2026-10-06 , Bridge 1-Short Workshops

The INTERLIS modeling standard and the QGIS Model Baker plugin provide everything you need to collect, manage and exchange harmonized data and ensure consistency, data quality and system independence. So let's have a look at it. This workshop provides an initial impression of INTERLIS and shows how easily you can use it in QGIS.

Authorities in Switzerland and Colombia use a model driven approach for collecting, managing and exchanging harmonized data. INTERLIS is the data modeling standard for geospatial data, ensuring consistency, data quality and system independence.

Model Baker is a QGIS plugin to create projects from plain text INTERLIS models including layer tree, forms, relationships and more.

In this workshop, we will explain the benefits of INTERLIS and guide you through the following workflow:
+ Analyze a conceptual model in INTERLIS
+ Convert a conceptual model to a database (ili2db)
+ Build automatic forms for data capture from your database (QGIS Model Baker)
+ Capture the data (QGIS)
+ Validate the data (QGIS Model Baker / iliValidator)
+ Exchange the data (ili2db)

This workshop is for INTERLIS beginners and people interested in this approach.

Requirements for the Attendees
+ QGIS LTR
+ Java Runtime Environment ( https://adoptium.net/ 1.6 or later) or openjdk (18)v
