Actueel Hoogtebestand Nederland (AHN, national elevation model)
The elevation map of the Netherlands, measured by laser from an aircraft: at least ten measurements per square metre. There are two maps. The terrain model (DTM) is the bare ground. The surface model (DSM) is everything on it, including buildings and trees. Via PDOK as a map layer (WMS), as a raster API (WCS) and as a download.

Rijkswaterstaat on ArcGIS Online
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)
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.

National Road Database (NWB) and road data
Rijkswaterstaat's National Road Database is the national road network as lines: every road with a street name or number, from motorway to residential street, split into road sections with road authority, municipality and hectometre markers. On 16 October 2026 that was 1,667,080 road sections and 162,114 hectometre points. 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.

Waterinfo and Water Web Services
Rijkswaterstaat's measurements in the major rivers, along the coast and in the North Sea: water level, discharge, water temperature, waves and more. A new value every ten minutes, and for some stations a series going back to 1900. Waterinfo is the website, the Water Web Services are the API behind it.
Examples with their data
Sand nourishments along the coast since 1952, volume by coastal section: most Maasvlakte (189.0 million cubic metres of sand), then Noord-Holland and Delfland
Rhine discharge at Lobith (monthly mean): 683 cubic metres per second in September 2026, 61% less than in September 2025
Road sections in the National Road Database by road authority: municipality is the largest part, 92% in October 2026
The relief of the hills around Valkenburg, from the Actueel Hoogtebestand Nederland
Bodemloket sites by supplying authority: most Omgevingsdienst Haaglanden (34,157 sites), then Omgevingsdienst West-Holland and Provincie Limburg
Bodemloket sites by next step: most sufficiently investigated (140,558 sites), then historical survey to do and exploratory survey to do
