I wrote a stored function in MySQL but it calculates just 1 for each row in select query. I came across a package (geopy) which can do this for me. As calculation of distance is mostly a data oriented job, it would be better to have the distance calculation procedure written as a T-SQL function. It's a complex formula so in this post, we'll find out how exactly this works, including a verification of the result. With geography datatype you can create system where you can filter locations on bases of distance between them. The first coordinate of each point is assumed to be the latitude, the second is the longitude, given in radians. Of course since you can have a column already defined in SQL Server 2008 with the geography of the location ( location_geography) you can more efficiently have: CREATE PROCEDURE [dbo]. Latitude Longitude Distance = REarth * 2.0 * atan2 ( sqrt (1-A), sqrt (A) REarth is the radius of the Earth in miles and A is defined as: Note that your coordinates must be converted fro degrees to radians for the formula to work. For large distances (over ~25 miles), this proved pretty inaccurate. I have placed the below measure into the values however it is showing the same distances between the candidates and sites for a lot and not calculating the correct distance. Currently it takes 18 seconds for the result set to be returned. . This function would required four inputs totally - latitude and longitude of both points. In this post, I will demonstrate how to calculate the distance and time between two points, either by entering the zip code, address or latitude and longitude. Other databases like SQL Server have the Geography datatype that does this relatively easily but I don't see anything similar .
