Airports and Aviation Infrastructure for Saint Helena, Ascension and Tristan da Cunha

OpenStreetMap data for airports, heliports, runways, terminals, and emergency landing sites across three remote British Overseas Territories. The Humanitarian OpenStreetMap Team (HOT) compiled this export, which includes features tagged with `aeroway`, `building`, or `emergency` keys. Completeness varies by region, with urban areas likely being better mapped than remote locations.

Use Cases

• Plan evacuation routes based on airport and helipad locations.
• Map logistics networks using aviation infrastructure data.
• Identify emergency landing sites for aerial-response planning.
• Analyze regional aviation connectivity from airport and runway data.

Strengths

• Data is provided in multiple geospatial formats (GEOPACKAGE, KML, SHP, GEOJSON, JSON).
• Exports are sourced from OpenStreetMap, a free, collaborative global mapping project.
• Includes a specific focus on aviation infrastructure tagged via `aeroway`, `building`, and `emergency` keys.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Completeness varies by region; remote areas may be incompletely mapped.
• Row count is unknown, which may limit suitability assessment.
