Smarter Geospatial Management: A Collaborative Web Client for National Spatial Data
2026-09-03 , Ran2

We present the Geonorge.Forvaltning.Client, a web-based GIS interface designed for the collaborative maintenance of Norway’s national map data. By lowering technical barriers for public administrators, this tool fosters inter-agency transparency and democratizes spatial data management, aligning with the FOSS4G spirit of open, accessible geospatial technology.


Maintaining accurate national spatial data infrastructure (NSDI) often requires specialized, heavy desktop software, creating silos between data experts and local administrators. The Geonorge.Forvaltning.Client ("Smarter" Geospatial Management) changes this paradigm.

Developed by Kartverket (the Norwegian Mapping Authority), this open-source web application allows diverse public entities—from small municipalities to national agencies—to collaboratively edit, manage, and analyze geographic datasets directly in the browser.

In this session, we will explore:
- The "GIS-lite" Philosophy: How the client simplifies complex GIS tasks (geometry editing, metadata entry, and tabular updates) for non-expert users.
- Dynamic Schema Management: Enabling users to define and modify dataset structures on the fly while maintaining strict data integrity through validation.
- Collaboration & Access Control: How the system manages permissions across organizational boundaries to ensure "Smarter Management".
- Real-world Impact: Case studies on how this collaborative approach improves the speed and quality of Norway’s map data updates.

This talk is ideal for developers and decision-makers interested in modernizing NSDIs using open-source web technologies and collaborative workflows.

Henrik Gulliksen Schüller is a self-proclaimed "Map Guru" and Product Owner at the Norwegian Mapping Authority. Armed with a Master’s in Geomatics from NMBU and a legendary distaste for messy manual configurations, he created Waystones to make OGC API deployment actually enjoyable. Henrik is dedicated to proving that publishing authoritative geospatial data shouldn't require a backend degree. While fluent in English and Norwegian, his elementary Japanese will be put to the test in Hiroshima—where he hopes his maps are much more reliable than his grammar.
