Google MapsThis looks pretty interesting... Found this on The Tao of Mac along with posts to some other interesting map tools... Take a look at Map24. A very slick Java based map web application. More about Google Maps below...
Maps are great for getting around, but online maps could be a lot better. So Google decided to make dynamic, interactive maps that are draggable — no clicking and waiting for graphics to reload each time you want to view the adjacent parts of a map. Want to be able to type in the name of a region or neighborhood and see any part of it as easily as with a regular street map? Now you can with Google Maps.
Since these maps are draggable, you can use your mouse or the directional arrows to pan left, right, up and down to see areas that are hidden offscreen. You can also use the slider to zoom in and zoom out.
It's like having a huge map you can scroll around in.
