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 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.
