Google Maps API map cutomization

I saw these maps in the websites of some universities 开发者_StackOverflowand I just loved them:

http://www.uottawa.ca/maps/

http://www.washington.edu/maps/

http://map.nd.edu/#/placemarks//zoom/16/lat/41.6993288511065/lon/-86.23415926449582

I would really like to do something like that in an Android app. I've been looking for a way to do it but I've found no clue. Since I'm new to this API I feel quite disoriented.

So, could you please point me in the right direction? Give me some hints, somo tutorials or whatever you think it can be useful.

You can get the mapview easily enough using the Google Maps API. Then you need images of whatever buildings you are proposing to put on the map. The images can be added to a map overlay which will appear on top of the map. The tricky part then, is to match the geo-coordinates of your buildings to the map so that when a user scrolls the map, the images move as well and also to scale the images as the user zooms in and out.
