Calculate online the great circle, the shortest distance between two locations on Earth.
16 kwi 2024 · The Great Circle Calculator is a navigational tool that pinpoints the shortest distance between two locations on Earth. By considering the planet's spherical shape, the calculator efficiently maps out the most direct route, also known as the great circle path.
The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations.
This calculator will find the straight-line (great circle) distance between two locations of any kind: street addresses, city names, ZIP codes, etc. (The coordinates of the locations are provided by the Google Geocoding API.)
