Google Earth

I downloaded Google Earth yesterday. I must say, I'm impressed. It does take a pretty up-to-date computer to run the software. You can find locations and statistics for sites worlwide. You get 3-D views for some cities and you can overlay maps on the satellite images. It will giver you the GPS coordinated of any object on its screen that you point the cursor at as well as height above sea level. It's an excellent step up for mapping software. Its biggest drawback and strongest attribute are that the info is streamed to the computer. It should allow for more accurate and timely info but makes its use on the road to be problematic. I'm not sure if the basic interface is available minus the rest of the data or not. I haven't tested that out yet. Still, its worth the free download.
