A collection of datasets from various Dutch institutions to demonstrate a Spatial Data Infrastructure built on Portolan.
Dutch Directorate-General for Public Works and Water Management. Rijkswaterstaat manages the main road and waterway networks and the water systems in the Netherlands.
Most of these collections were downloaded from Rijkswaterstaat's public ArcGIS Feature Services, converted to GeoParquet and PMTiles for cloud-native access. The original Feature Services remain the authoritative source and may be updated more frequently.
