Great Circle Calculator. By Ed Williams. ... 5/16/98 Changed the great circle radial and distance algorithm to one valid for unlimited distances. Previous was only valid for ranges up to one quarter of the earth's circumference in longitude. Note that the Vicenty algorithm for (ellipsoidal) course and distance may fail to converge correctly, or ...

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!
18 sty 2024 · In our great circle calculator, we went for the WGS 84: a widespread model used even by GPS satellites. Here are the numbers: a = 6378137.8 m. a = 6 378 137.8\ \mathrm {m} a = 6378137.8 m; b ≈ 6356752.314140 m. b \approx 6 356 752.314140\ \mathrm {m} b ≈ 6356752.314140 m; and. f = 298.257223563.
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.
Great-circle distance between two points. Enter the co-ordinates into the text boxes to try out the calculations. A variety of formats are accepted, principally: deg-min-sec suffixed with N/S/E/W (e.g. 40°44′55″N, 73 59 11W), or. signed decimal degrees without compass direction, where negative indicates west/south (e.g. 40.7486, -73.9864):
Calculate the great circle distance between two points. Calculate the great circle distance between two addresses. Draw a direct route between two airports, or multiple airport pairs. Draw range rings (concentric circles) around a point. Calculate coordinates at a given bearing and distance.
Latitude/Longitude Distance Calculator. Enter latitude and longitude of two points, select the desired units: nautical miles (n mi), statute miles (sm), or kilometers (km) and click Compute.
