Rijnland water authority geoservices (ArcGIS REST)

Hoogheemraadschap van Rijnland

The ArcGIS server of the Rijnland water authority, hosted by a supplier (enl-mcs.nl). Almost every service is one type of managed asset: valves, culverts, pumping stations, weirs, watercourses, flood defences. On 16 October 2026 our index held 230 layers; the current register of structures alone has 57,032 features and the watercourses 187,861 line segments. Rijnland is not listed as a publisher on data.overheid.nl or in the National Georegister, so this is the only public entry point. On reuse, Rijnland itself says it is not allowed without permission; we only show descriptions and counts.
