Dont know if anyone knows about this, but it is a really cool program allowing you to use LandSAT data and USGS 1m Black and White and Color to zoom into anywhere in the world.
http://learn.arc.nasa.gov/worldwind/download.html
check it out, it is really cool! be patient with the LandSAT Stuff, it takes a while to load, and might be down as it was on slashdot, and the nasa servers took a big hit from the increase in traffic. So please make sure to register on the nasa forum if you have any questions about not being able to download the landsat or if you get a message "Unable to connect to server--blah blah blah". overall it is pretty cool.
you can download "cache's" of the landsat data, so that you wont have to connect to the server, but they are around 50mb-500mb a peice.
The WorldWind Program 1.2c is a 254mb download, PLEASE read the system requirements before installing!
