Weekly Map 7: Zooming and Panning

I'm very familiar with this example of good zooming and panning. I like that you can use a traditional zooming tool with a rectangular selection. I also like that you can pan and get info on a particualr map with the same tool. Very cool.



This USGS service gives you access to thousands of Geologic maps in the US.

It's called the National Geologic Map Database (NGMDB)
