Some of the answers do refer to Vincenty's formula for ellipsoids, but that algorithm was designed for use on 1960s' era desk calculators and it has stability & accuracy issues; we have better hardware and software now. Wikipedia: Haversine; Wikipedia: Vincenty; Is the Haversine Formula or the Vincenty's Formula better for calculating distance? Example. 1. – Does WGS84 vs GCJ02 coordinates impact the calculation or distance (The Vincenty's formula takes the WGS84 axis into consideration)? For example, in Android, the Haversine Formula is used in Google Map Utils , but the Vincenty Formula is used by the android. Hence, Vincenty's formula is a few orders of magnitude more accurate, not ~0. Vincenty is more accurate than Haversine because is considers the Earth's ellipticity when performing the calculation, but takes a longer time to compute. There are five types of price elasticity of demand. Now that we know what the radius of a circle is (marked with green), let's get familiar with the rest of the lines.
