Geospatial Data Collection with 3D Models and Disaster Information

A curated collection of publicly available geospatial datasets from the Geospatial Information Center that specify a Creative Commons license. The data includes 3D city and building models, elevation and terrain data, vector datasets for administrative boundaries and land use, and disaster-related geospatial information. The collection is hosted on AWS S3 and aggregated by the organization AIGID.

Use Cases

• Create 3D urban simulations based on CityGML building models mentioned in the description.
• Analyze terrain and flood risk based on Digital Elevation Model (DEM) data.
• Map administrative regions and land use patterns using the described vector datasets.
• Model disaster scenarios and hazard exposure using the included disaster-related geospatial data.

Strengths

• All datasets explicitly specify a Creative Commons license, ensuring clear reuse rights.
• The collection includes multiple geospatial data types useful for integrated analysis, such as 3D models, elevation data, and vector boundaries.
• Data is hosted in an AWS-friendly manner on S3, facilitating cloud-based access and processing.

Limitations

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