I've been programming with Google Maps API since 3.6. I have been using google.maps.GroundOverlay. So what is the difference between this and USGSOverlay?

The core difference is ,that GroundOverlay is a part of Google Maps V3 API, but USGSOverlay is not.USGSOverlay is just illustrutation of OverlayView's implemenation, which you need add to your code , whenever you want to use it,but in GroundOverlay's case ,it is not neccessary. It is coming with Google Maps API's script. The other difference is, you can specify opacity of overlay in GroundOverlay's case, but you can't do that thing by USGSOverlay(you need to customize the code a little bit to achieve this).
