He can use what he likes, when properly informed. It's not difficult to find discussion of Haversine in the language and context of choice for any interested person. > Otherwise, for distances under a few hundred miles (other > than at Latitude 90 or -90) my formula should work (assume latitude is > "y" and longitude is "x"). For moderate latitudes, error could be in the order of 30%, and will apply to distances of miles or metres. That might be fine for the orginal poster, so long as they understand the limitations of using degrees as a form of distance measurement away from the equator. For the original poster, have a look at some of these http://www.google.com/search?q=lat+long+distance just calculate the distance between two points, convert it to miles or metres or whatever you want, and compare it with the search requirement. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
