haversine

问题 Problem I would like to know how to get the distance and bearing between 2 GPS points . I have researched on the haversine formula. Someone told me that I could also find the bearing using the same data. Edit Everything is working fine but the bearing doesn\'t quite work right yet. The bearing outputs negative but should be between 0 - 360 degrees. The set data should make the horizontal bearing 96.02166666666666 and is: Start point: 53.32055555555556 , -1.7297222222222221 Bearing: 96

问题 How do I calculate the distance between two points specified by latitude and longitude? For clarification, I\'d like the distance in kilometers; the points use the WGS84 system and I\'d like to understand the relative accuracies of the approaches available. 回答1: This link might be helpful to you, as it details the use of the Haversine formula to calculate the distance. Excerpt: This script [in Javascript] calculates great-circle distances between the two points – that is, the shortest
