This demo shows you the basics of using the Google Maps API. I have an array of sample date that get dropped around New York, while it will also ask you to authorize your computer (if it has GPS), so that it can figure out where you are. The basic Idea is to use Google Maps so that you’re able to Geo-tag places and leave notes (think Foursquare, Google+ checkins, or FB checkins). The idea was anyone can use the site and post ‘mainly’ anonymous messages about anything with a gps location. Of course for the sake of this demo I’m simply allowing you to click anywhere on the map and add a marker.
