Question

Problem

I have two coordinates: A B

Solution?

Can I see if coordinate A is within 50 meters of coordinate B using Google Maps API?

Other Solution?

If not, is there a way to do this without using google API?

Answer 1

computeDistanceBetween() from the Google Maps API v3 geometry library returns the straight line distance between two google.maps.LatLng objects (the default units are meters).

Be sure to include the geometry library

Answer 2

Each phone, amd many other geo apis have a function to calculate the distance between two lat,lon coordinates.

If you dont have one, then use the haversine distance formula.
