The formula used to calculate the distance between two geographic points is called 'orthodromy' and is defined as follows:

This formula takes into account the curvature of the Earth: Distance(A,B) = 3959 * ACos( Cos(LatA) * Cos(LatB) * Cos(LngB - LngA) + Sin(LatA) * Sin(LatB) )

The result is the distance in miles between point A and point B.

Our clients have access to a free collection of codes (PHP, ASP) in the client area.

A database of places with their latitudes (lat) and longitudes (lng) allows you to locate the cities closest to a given point (or within a radius of X km):

This formula takes into account the curvature of the Earth: SELECT Name, 3959 * ACos( Cos(RADIANS(Lat)) * Cos(RADIANS(UserLat)) * Cos(RADIANS(UserLng) - RADIANS(Lng)) + Sin(RADIANS(Lat)) * Sin(RADIANS(UserLat)) ) AS Distance FROM Cities ORDER BY Distance

The values of UserLat and UserLng must be replaced with the coordinates of the point given. To limit the search to a specific radius, you can add a WHERE clause to the distance; you can also specify a LIMIT clause to display only the X cities closest to your given point.
