Use Great Circle Mapper to calculate the distance and flight duration between all airports worldwide and draw the flight route on a map.
Enter lat/lon of initial point, true course and distance. Select distance units and earth model and click "compute". Lat/lons may be entered in DD.DD, DD:MM.MM or DD:MM:SS.SS formats.
Great Circle Map displays the shortest route between airports and calculates the distance. It draws geodesic flight paths on top of Google maps, so you can create your own route map.
Simply enter any desired location into the search function and you will get the shortest distance (air line) between the points, the route (route planner) as well as all important information. Of course, you can also determine distances between coordinates (latitude / longitude).
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.)
Distance Units: Earth model: Javascript Great Circle Calculator using ellipsoidal earth models.
The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations.
