GIS Resources

There's lots of GIS resources on the 'net, and even though Google is pretty good at helping you find what you want, I thought it might be interesting to see if we could use a wiki to organize the information in an even more useful way. Since there are a lot of things that might fit into this category, I'll be interested to see how this page evolves... - BillThoen?
