Crop parcels (BRP) and reference parcels

Rijksdienst voor Ondernemend Nederland (RVO), via PDOKNetherlands, parcel

Every year farmers tell RVO which crop grows on their parcels. From those declarations RVO builds the crop parcel register: each parcel as a polygon, with crop, crop code and category (grassland, arable land, landscape feature, nature area …), reference date 15 May. The API holds the final 2025 edition with 2,331,084 parcels; the downloads go back to 2009 and a draft for 2026 is already available. Also the reference parcels: the outline of all agricultural land (2,358,200 polygons), formerly the Agrarisch Areaal Nederland. Via PDOK as OGC API, WFS, WMS and GeoPackage.

Heat potential maps (WarmteAtlas)

Rijksdienst voor Ondernemend Nederland (RVO), WarmteAtlas Nederland, via PDOKNetherlands, neighbourhood (2014 boundaries)

Four map services from RVO's WarmteAtlas: the potential for underground heat and cold storage (WKO) per neighbourhood and municipality, biogas and woody biomass per municipality, a map of 2,283 business sites with their CO2 emissions for estimating residual heat, and a raster map of WKO potential in GJ per hectare per year. Mind the age: the neighbourhood and municipal figures are for 2014 (403 municipalities, the boundaries of that time) and the CO2 figures run to 2013. The dates on PDOK (2024 and 2025) are publication dates, not reference dates.
