a call for collaboration

cross border data exchange

24 februari 2026

We invite you to join us! Help us identify data limitations currently holding back your work, and develop practical solutions together.

The spatial challenges we face today housing, mobility, energy, climate… can no longer be addressed within administrative and national boundaries alone. They require an integrated, cross-border approach.

With this expression of interest, we share our ambition to mobilise and advocate for an accessible, GIS-based cross-border data infrastructure. Building on conversations with staff at Statistics Netherlands (CBS), and in coordination with partners at the Creative Industries Fund NL (Stimuleringsfonds voor de Creatieve Industrie), we propose starting with a minimum viable GIS interface. This interface would connect key datasets from e.g. CBS, Statbel, the Nationaal Georegister, and Geopunt through APIs. The Deltametropolis Association is ready to coordinate this effort.

At the Deltametropolis Association, our roots lie in the Dutch Randstad area. Twenty-six years later, we have expanded our horizon with a shared ambition: to envision, redesign, and strengthen the Rhine–Meuse Delta as an international metropolis, one that transcends borders and connects with the Flemish Diamond and the Ruhr area as part of the broader Eurodelta. Through initiatives such as the Next Generation Podium and our research by design on rail embassies, and during last year’s cross-border transition events, including the September session “Transgression of European Border Regions”, a clear need emerged: stronger coordination of cross-border data. Fragmented datasets. lacking relational cross-border data and inconsistent access currently limit spatial development, regional collaboration, and innovation across the Eurodelta.
