Add details and clarify the problem by editing this post. Important in navigation, it is a special case of a more general formula in spherical trigonometry, the law of haversines, that relates the sides and angles of spherical triangles. This distance is also same as the Google distance and the distance calculated by MYSQL. Let’s try out a simple exercise to find out the nearest walmart from the origin(i.e. I want to undershoot, as this will be for A* graph search and I want it to be fast. Here are three abstractions which is considered for calculating the distance between two lat and longs: The shortest distance between two points in a plain is a straight line and we can use Pythagoras Theorem to calculate the distance between two points. I'm trying to solve the problem of interpolating a point at a given distance (in meters) between two other lat/long points. Then I will demonstrate the basic distance calculation between two points on a map given their coordinates. This distance between two lat/longs is based on some level of abstraction and it’s not an exact distance, which is unattainable if you are considering all the irregularities on the surface of earth. In order to calculate the distance, we have to convert the latitude and longitude values from degrees to radians. The Geodesic distance is also 28 KM which is same as the Spherical and Pythagoras distance that we calculated above. geopy makes it easy for Python developers to locate the coordinates of addresses, cities, countries, and landmarks across the globe using third-party geocoders and other data sources.
