Is there a way to create geo location search of closest points with javascript? for example, we have a list of points with their coordinates. I need to find points ~ in 5km radius.

You want the harvesine-formula for Javascript and Google Maps.

You want to look for a space-filling-curve too. I've done an implementation in php ( hilbert-curve ). You can download it at phpclasses.org ( hilbert-curve ). – Micromega Mar 25 '11 at 11:43
