The box indicates clearly the area covered and there is a listing of the exact USGS maps and their revision dates that can be viewed from inside the tool. Unlike some raster scan graphics maps there is the illusion of intelligence on these maps. Overall however the ability to search a map is a nice feature. The set I purchased had coverage including more that 200 USGS maps. Other sets have either 100 or 200 maps depending on whether they are single or 2 cdrom sets.
Price is the same.
The optional gps tools include the ability to upload, download waypoints and routes to a gps unit as well as the ability to dynamically track the gps reported location on the map and to create a track. You can also reverse the track to retrace your route. Like almost any program with a zero at the end of the version number this program has a few significant bugs. I have already mentioned that some users can't use the magnify option as there video cards aren't supported and that the bookmark command is missing from the menu. My printer, a Lexmark 5700 won't print full pages.
