North Holland Province geoservices (ArcGIS REST)

Provincie Noord-HollandNetherlands, feature (province of North Holland)

The ArcGIS server of the province of North Holland, with nearly 200 services in the root and six subfolders. On 16 October 2026 we counted 3,843 leaf layers on the server; because the same layer recurs in many collection services, our index keeps 2,683 after deduplication. Three quarters sit in the oi_op folder (environmental information), including a time series of the provincial environmental regulation, the provincial monuments and the nature management plans per year. Almost none of this is on data.overheid.nl or in the National Georegister.
