Description
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.
