Provincie OverijsselNetherlands, feature (province of Overijssel)

The ArcGIS REST server of the province of Overijssel: 45 services, each a theme with a B code (B22 roads, B42 energy, B46 nature and landscape, B73 culture …). On 16 October 2026 our index held 436 map layers, together over 20 million features (duplicate layers included), from energy labels of 503,016 homes to 4,040 national monuments. About 60 percent of the layers are also in the National Georegister, as WMS/WFS on the province's GeoServer; this server mainly adds per-feature queries and counts.
