As I mentioned in the article Extending Google Maps API 3 with libraries a couple of weeks ago, you can add functionality to the Google Maps API by using libraries. One of these libraries are the Geometry Library. In this article I will show how you can use the function of that library to calculate distances and areas. I will also explain some additional navigation functions that you might find useful.
In the latest version of Google Maps API 3 (version 3.4) a new exciting feature is introduced: 45° imagery in selected cities around the world. This feature will let you see the world from a whole new angle. This change also calls for new properties and controls for the Map Object which will all be explained in this article. As a bonus I will also introduce you to another new feature, the brand new Map Overview Control.
