We don't seem to have a Google Maps forum, although it is easily a topic big enough to deserve one (hint-hint), so I'm asking this here.
First, the application: I have an interface that fills a browser window with a Google Map. There is a marker, surrounded by a radius. The user can drag the marker or click on the map, and the marker moves there. Local points of interest appear within the radius as clickable markers.
What I would like to be able to do is give some feedback to the user as to where they are when they click. Since they can click arbitrarily, I would like to be able to give them some information, like "You are in Muttontown, NY" or "Glen Cove Road at Smith St.," etc.
I know about this [google.com], but I need the opposite. I need to feed in coordinates and get back some address information.
