Overlay ability in vaadin on google maps add on

I am looking for a feature which is available on vaadin/GOOGLE maps API/Google web toolkit which allows to overlay custom indoor maps OR images over a particular latitude/longitude on google maps.

I found something that is available on android GOOGLE Maps api, following is the link for that.

However, i am not able to find something exactly similar for desktop based web interface.

I am using vaadin 7+ with google maps add on

Thanksgoogl
