Advanced tools
Translate latitude and longitude values into 'world' coordinates as used by the Google Map API.
Whenever the Google Maps API needs to translate a location in the world to a location on a map (the screen), it needs to first translate latitude and longitude values into a "world" coordinate. This translation is accomplished using the Mercator projection.
