Product Description TOPO! harnesses the power of authentic USGS topographic maps in an intuitive software product that recreation enthusiasts and professionals use to customize and print photo-quality topographic maps. TOPO! includes five levels of seamless mapping, including USA maps from the National Geographic World Atlas, USGS 1:100,000 scale mapping - perfect for back road navigation - and USGS 1:24,000 scale maps, also known as 7.5 minute quads. Users can custom-center the map in any location, add their routes, trails and notes. In addition, users can transfer waypoints and routes between TOPO! and their GPS units.

Users can download map and software updates, and can print waterproof maps on their inkjet printers with Adventure Paper (sold separately). The USA "Place-Finder" locates more than a million places and natural features. With the TOPO! Texas, National Geographic has taken the interactive topographic map experience to a new level.

State Series offers map detail that is unprecedented in its accuracy. Simply load TOPO!, and you'll immediately begin to see the benefits of this award-winning software. With TOPO! you can customize any of the hundreds of state maps available with your proposed routes, notes and even photos. You can also create and view elevation profiles that will help you visualize your planned trek.
