WebSep 7, 2024 · Haversine distance is the angular distance between two points on the surface of a sphere. The first distance of each point is assumed to be the latitude, while the second is the longitude. Both these distances are given in radians. In the Haversine formula, inputs are taken as GPS coordinates, and calculated distance is an approximate value.
