Calculate the great circle distance between two pointsThis calculator will find the distance between two pairs of coordinates to a very high degree of precision (using the thoroughly nasty Vincenty Formula, which accounts for the flattened shape of the earth). The "Draw map" button will show ...
Displays a map on which the great circle path for one or more routes is plotted and calculates the distance along each route. Ranges from one or more locations may also be plotted, along with go/no-go areas for ETOPS operations at various ru
This calculator requires the use of Javascript enabled and capable browsers. This script allows calculation of Great Circle navigation information, and the eventual desired waypoints for a long journey. For navigation purposes, the definition of a great circle is a circle on the surface of the ...
The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations.
on a known system of projection a selected great circle of reference such as a prime meridian orthogonally cut by a family of curves representing a series of great circles which are rational horizons for selected points on the circle of reference, and another set of curves representing azimuths...
