Google Map API

Ever wondered how to keep a map to show your current location in your site.If you know the longitude and latitude of your location..then the Google maps will serve this purpose.You can place markers on the map,set route paths..and what not...

These are widely used for GPS tracking systems now a days.Including just a sample code to explain the same would be a sin as you will never be able to explore its full features if you really dont go around this.This link will help you find the full documentation for the same..
