About 3D maps

View 3D perspectives of land and cities using the mouse, keyboard, or an Xbox 360 Controller for Windows.

With the navigation control you can view cities and streets from different heights and angles. Latitude, longitude, and altitude appear in the lower-left status bar of the browser window. A scale bar in the lower-right corner of the map indicates the distance from your viewing point to the objects below you.
