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 ...

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.
18 sty 2024 · To calculate the great circle distance on a sphere, take the points A = (φA, λA) and B = (φB, λB), and follow the steps: Compute the product of the cosines of the latitudes and the difference of longitudes: t1 = cos (φA) × cos (φB) × cos (λA - λB) Compute the product of the sines of the longitudes:
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. Coordinate Converter.
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.
