I remember writing about this here.
"Now, what's possibly next from Google (or MSN or Yahoo)? Use your imagination. What would you like to put on top of that map? Er, image? I got a few things. How about a sushi icon? Huh? Click the sushi icon and it takes you to all the nearest sushi restaurants. How about a camera icon? Click on that and it takes you to all the nearby photo opportunities. How about a Hospital icon? Click that and it takes you to the closest hospital. How about a blog icon? "
I'm thinking that the next best thing to be layered is, GPS (Near Real Time Coordinates) being Mapped onto current Map Platform. In this manner, all the users needs to do -is actually type in my Cell Phone Number or whatever and he'll actually see my physical location on Web. Then s/he can zoom in and out to see further information for the location.
Direct Satellite Positioning ? I nipped and tucked something a while back.
