BAG provides a national registry of buildings, addresses, residences, and public spaces in the Netherlands, each with associated geometry. The Amsterdam municipality supplements this with legally mandatory BAG-plus features, such as building names and specialized function classifications. Data is provided by the Dutch Ministry of the Interior and Kingdom Relations under a CC0-1.0 license.
Use Cases
- Geospatial analysis of building footprints and public spaces based on the geometry data.
- Address validation and standardization using the national address and number indication registry.
- Urban function mapping based on the specialized use purpose and use target classifications.
- Building height analysis using the number of building layers and highest/lowest layer attributes.
Strengths
- Includes legally mandatory BAG-plus features for Amsterdam, providing municipal-level detail.
- All objects contain geometry, enabling spatial analysis and mapping.
- Available in multiple formats including CSV, JSON, and ESRI SHAPE for flexibility.
Limitations
- BAG-plus features are currently only filled for objects in Amsterdam, not Weesp.
- Column-level documentation is absent; field semantics must be inferred after download.
