USGS topo maps are the recognized standard for off-road navigation. Maptech scans official paper maps to produce clear and detailed images of all 58,000+ USGS maps. Each CD-ROM contains up to 300 quads in two scales: 1:24/25,000 (7.5 minute series) and 1:100,000.

View maps in 2-D or bring contour lines to life in 3-D. You also have the option of putting 2-D and 3-D side-by-side.

Scroll seamlessly from map to map, or view individual maps, complete with border and legend information - a Maptech exclusive. Here's an example of the seamless intersection of 4 maps:

View and print cross-sections and line-of-sight profiles with the latest high-resolution digital elevation data.

Customize your maps with marks, routes, symbols and notes.

Join adjacent maps together in a single printout (even at 4-corner intersections), either as a flat map or in 3-D. Add marks, routes, notes and symbols to your personal map.

Turn your PC into a moving map display. Connect a GPS and you'll see your position right on the screen.

Upload and download marks and tracks, but not maps, between your PC and popular GPS receivers.

Download the maps to a Pocket PC running Pocket Navigator (sold separately).
