USGS topo maps are the recognized standard for off-road navigation. MyTopo scans official paper maps to produce clear and detailed images of all 58,000+ USGS maps. Each DVD contains nearly one thousand different maps in three scales: 1:24/25,000 (7.5 minute series), 1:100,000, and 1:250,000 scale. Additional map types (such as shaded relief) are available for 1:24/25,000 scale topo maps (via download.) Note: The Alaska DVD set contains 1:63,360 and 1:250,000 scale topo maps only.
