BGT: Large-scale Topographic Map of the Netherlands with 20cm Accuracy

Basic Registration Large Scale Topography (BGT) is a digital map of the Netherlands recording buildings, roads, watercourses, land, and railway lines. The dataset is provided by the Ministerie van Binnenlandse Zaken en Koninkrijksrelaties under a CC-BY-4.0 license. Its accuracy is stated as 20 centimeters and it contains many real-world details like trees.

Use Cases

• Urban planning and development analysis based on detailed building and road data.
• Environmental modeling and flood risk assessment based on watercourse and land data.
• Infrastructure planning and analysis based on railway line and road network data.
• Creating realistic 3D city models or simulations based on the detailed physical environment data.

Strengths

• Accuracy is explicitly stated as 20 centimeters.
• Contains many real-world details such as trees, roads, and buildings.
• Covers a defined national geography (the Netherlands).

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.
