title: How to draw coverage area on Google Map?
body: <p>Basically I have some school catchment map that I would like to put on Google Map. I have done some research but it seems that we can only draw polylines. For example, I like to draw the red line from the <a href="https://www.dropbox.com/s/7i8klbmdbbhkj1z/van_school_catchment.png" rel="nofollow">attached image</a> onto Google Map, how do I do that? Any tip or point of direction would be very appreciated!!</p>
