Calculate distance and bearing between two Latitude/Longitude points using haversine formula in JavaScriptThis page presents a variety of calculations for latitude/longitude points, with the formulas and code fragments for implementing them. All these formulas are for calculations on the basis of a spherical earth (ignoring ellipsoidal effects) – which is accurate enough* for most purposes… [In fact, the earth is very slightly ellipsoidal; using a spherical model gives errors typically up to 0.3%1 –
