Geocoding Google Map

In one of my projects, I needed to dynamically add overlays to the Google map for group of users . Basically, overlays can be added to Google map using latitude/longitude coordinates. In my case the trick is I don’t have the latitude/longitude for the users, I have the user addresses entered from sign up process.

Google provides geocoding to get the latitude/longitude from any address.

Please note:

It is not an exact match but works for my requirements. The following is the code to achieve this.

    var PIcon = new GIcon();

    PIcon.iconSize = new GSize(32, 32);
    PIcon.iconAnchor = new GPoint(9, 32);
    PIcon.infoWindowAnchor = new GPoint(9, 2);
    PIcon.infoShadowAnchor = new GPoint(18, 25);

    var map = null;

        geocoder.getLatLng(address, function(pt) {

                var marker = new GMarker(pt, PIcon);
                map.addOverlay(marker);
