The Google Earth navigation controls offer the same type of navigation action that you can achieve with
mouse navigation. In addition, you can use the controls to tilt the view (perhaps for a perspective on terrain) or
to rotate the viewer around the center. The following diagram shows the controls and explains their functions.
1. Use the tilt slider to tilt the terrain toward a horizon view. Move the slider to the left for a top-down view
or to the right for a horizon view. Double click the icons at the end of the slider to reset the tilt all the
way to a top-down view or to a horizon view.
2. Use the joystick to move the center point of the view down, up, right or left. Click the center, hold the
mouse button, and move in any direction.
3. Click the direction arrows to move the view in the direction you wish.
4. Click the north up button to reset the view so that north is at the top of the screen.
5. Use the zoom slider to zoom in or out (+ to zoom in, - to zoom out). Double click the icons at the end of
the slider to reset the zoom all the in or out.
6. Click and drag the navigation ring to rotate the view.
You can also use the keyboard to control navigation, see
