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.
The Great Circle Mapper Draw you flight path on a map and calculate the great circle distance in nautical miles and kilometers. Get estimated flight time by choosing an aircraft type or entering the cruising speed.Click in the large textfield above to enter all the airports of your flight route!
The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations.
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. Note that the starting point cannot be a pole.
This calculator computes the great circle distance between two points on the earth's surface. The program is operated by entering two geographic points and then pressing the Calculate button. The entry form allows you to enter geographic position in degrees, minutes, and seconds.
You can enter airports, cities, states, countries, or zip codes to find the flying time between any two points. The database uses the great circle distance and the average airspeed of a commercial airliner to figure out how long a typical flight would take.
