Delorme's Topo USA & Microsoft's Streets and Trips provide GPS coordinates. I've been using Topo USA for several years and it's always been very accurate. I like Streets and Trips because it takes up a lot less space on the hard drive but still provides some decent mapping features. Topo USA has more terrain/elevation detail and info on things like springs, old mines, streams, etc. but it uses up almost 3gb of disk space if you decide to load all the map data to the hard drive.
