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.
