Rijkswaterstaat on ArcGIS Online

RijkswaterstaatNetherlands, feature (national roads, national waters, coast)

The services Rijkswaterstaat hosts in its own ArcGIS Online organisation: 474 feature services and a WFS. On 16 October 2026 we tracked 2,120 of their layers (excluding read-only copies ending in _view). Unlike the provincial servers, every layer has a last-modified date: 650 layers were updated in 2026, the newest on 15 October. It holds yearly traffic volumes on national roads (Inweva 2014 to 2025), every sand nourishment along the coast since 1952, climate risks for the main road network, charging stations, truck parkings and many project maps.

Bodemloket (soil information desk)

Rijkswaterstaat, met gegevens van provincies, omgevingsdiensten en gemeentenNetherlands, site (plot or polygon)

Where has the soil been surveyed, where is it contaminated and what is being done? The Bodemloket shows what provinces, environmental services and large municipalities supply about their sites: the stage of investigation, the verdict on the contamination and whether it was remediated. On 15 October 2026 it covered 241,945 sites.

Plus NWB Waterways (4,825 waterway sections) and Road Data (WEGGEG) with speed limits and lanes on national roads, linked to the road sections. Via PDOK as OGC API, WFS and WMS.
