Satellite imagery

Let me give two links for Google Earth users. First one is Google Earth Hacks and second one is Google Sightseeing. Check them out!!! And if you like Google Earth, you should also try this World wind developed by NASA. About World wind Kate Russell from BBC wrote:

NASA's Goddard Space Flight Centre has produced a set of fascinating animations that demonstrate a variety of subjects such as hurricane dynamics and seasonal changes across the globe. Just like Google Earth, though, the real draw is the graphics. For example, have you ever wondered what it would be like to fly through the Grand Canyon or across the Swiss Alps? World Wind uses NASA's Landsat satellite imagery and Shuttle Radar Topography Mission data to allow you to zoom in from orbit and actually fly into and through famous landmarks and geographical wonders. Its full functions are way too complex to cover here so I will give you the best tip possible to get you started: launch the application and click Help followed by Key Chart. Be sure to explore all the different rotational and zoom options for the absolute best results.

Ohhh... don't ask me. I haven' try it yet. I'm quite busy these days and trying to run such kind of application would be time consuming on a antique PC like mine. And... Here are two links I took to compare Google and MSN online satellite images. . http://virtualearth.msn.com/default.aspx?cp=34...  tip: close "welcome" box to get wider view. . http://maps.google.com/maps?ll=34.031465,-118...
