Summary: Easy to Use Maps on CDs
Review: TrailSmart/Topo offers the best Maps on CD that I've seen, at least for people like me - hard core hiker, map nerd and computer geek. The viewer allows seamless display of USGS 7-1/2 minute quads as you pan across, up and down exploring the cyber world. You can draw your trips on the maps, add text labels and symbols; and print them out on your color printer. You can also download tiny .tpo files from the topo website where people like me share their favorite trips with you.Each area covered comes with maps at 4 or 5 levels of zoom - so you can make good driving and overview maps - and still get all the detail you need. The closest version is usually 1:24,000 (regular USGS 7-1/2 minute) and contains most of the information found on the quads. (Some areas of coverage do not go down to 1:24,000 and are not useful for hiking). I use the Zion, Arches and Grand Teton Sections, and have not used the others. It really helps to have a color printer to print the maps out.
