The Google Earth Compass03 Dec 2009
If you’ve used Google Earth on the iPhone or iPod Touch have you ever visited one of the poles? If you do be sure to check out the compass in the top right corner of the screen. If for example you zoom in on a point roughly 90°N & 135°W you will see the compass rotate and spin freely.
Obviously the Google Earth compass is not magnetic but I thought it was interesting to note this curious feature and that it is not repeated on the Windows desktop application.
