I managed to get Google Earth, before downloads were temporarily suspended. The 3D terrain visualization is impressive, though high-resolution imagery is not available for many areas of Canada (the Rocky Mountains, for example). The software is very user-friendly and allows the image to be rotated and tilted and provides hours of fun. Google Earth is yet another winner from Google (though it would be interesting to see how they monetize all these free products). The image above is that of downtown Ottawa, showing the Parliament Buildings, Ottawa River and the Rideau Canal.
