Hong Kong Building Footprints and Attributes from OpenStreetMap

An OpenStreetMap export from the Humanitarian OpenStreetMap Team, last updated on 2026-03-03, includes all features tagged as buildings in the Hong Kong Special Administrative Region. The dataset likely contains attributes such as building name, type, levels, materials, and address components. It is available in multiple geospatial formats including GeoPackage, GeoJSON, and Shapefile.

Use Cases

• Mapping building density and distribution based on geospatial footprint data.
• Analyzing building types and functions based on the 'building' and 'office' tags.
• Estimating urban structure based on attributes like 'building:levels' and 'building:materials'.
• Geocoding and address validation based on fields like 'addr:full', 'addr:housenumber', and 'addr:street'.

Strengths

• Data is derived from OpenStreetMap, a collaborative global mapping project.
• Includes multiple name fields ('name', 'name:en', 'name:zh') for multilingual support.
• Available in five common geospatial formats (GARMIN IMG, GEOPACKAGE, GEOJSON, SHP, KML).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and contributor bias inherent to OpenStreetMap.
