Javascript – Finding all the markers inside a given radius


Input: Given a specific co-ordinate (latitude and longitude) and radius
Output: Displaying all the markers which reside under that circle from given list of markers.

How can I do this in google maps?

Best Solution

Just iterate all the markers you have and use the following function to get the distance from the specific co-ordinate to the marker: computeDistanceBetween():

To compute this distance, call computeDistanceBetween(), passing it two LatLng objects.

I found it over here. Then just filter out all the markers that turn out to be close enough.
