"TOPO! is easy and fun to use...A+". PC World, October, 1997
USGS topographic maps are a basic accessory for a wide range of outdoor activities. Now you can own a complete, regional set of maps on CD-ROM that can be browsed, customized and printed. Going beyond street map software, TOPO! provides the level of detail, elevation data, and powerful tools necessary for planning outdoor pursuits. TOPO! is a great compliment to your GPS.
Each CD-ROM contains complete full-color digital USGS topographic maps, each with 5 levels of magnification, ranging as detailed as 1:12,500. After choosing and marking your route, you can print an elevation profile of the route. An index lets you find key natural features or place names and then move straight to their location.
