Javascript Great Circle Calculator using ellipsoidal earth models.
Given a start point, initial bearing, and distance, this will calculate the destination point and final bearing travelling along a (shortest distance) great circle arc. Destination point along great-circle given distance and bearing from start point
26 sie 2008 · This script [in Javascript] calculates great-circle distances between the two points – that is, the shortest distance over the earth’s surface – using the ‘Haversine’ formula.
Calculate great circles routes as lines in GeoJSON or WKT format. Algorithms from https://edwilliams.org/avform.htm#Intermediate. Includes basic support for splitting lines that cross the dateline, based on a partial port of code from OGR.
27 lis 2019 · However, the calculation of the Great Circle Distance from two coordinates is simple, although I suspect generations of midshipmen might not have agreed. In this post I will write a short JavaScript application to calculate the distance from London to various other cities round the world.
