BAG: Addresses and Buildings Registry for the Netherlands

The Netherlands' Basic Registration Addresses and Buildings (BAG) is a government-managed registry containing details for all properties in the country. Municipalities are the source holders responsible for data inclusion and quality, with the Land Registry managing the central supply. The data includes five object types—buildings, residences, number indications, public areas, and residences—with attributes such as status, surface area, geometry, coordinates, construction year, and purpose of use.

Use Cases

• Urban planning and development analysis based on building purpose of use and construction year.
• Geocoding and address validation services based on the national address and coordinate registry.
• Spatial analysis and mapping based on building geometry and surface area data.
• Demographic and housing studies based on the inventory of residences and buildings.

Strengths

• Covers all properties in the Netherlands, providing national completeness.
• Includes multiple object types and attributes like geometry, coordinates, and construction year.
• Managed by a central government authority (Land Registry) with municipal source control.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
