DeLorme Topo USA CD-ROM
Topo USA allows you to create your own topographic maps for the
entire U.S., with automatic trail and road routing. You can scout terrain with realistic
shaded relief or 3-D views, and upload or download points to or from the most popular GPS
receivers. View UTM coordinates, GPS grids, and instant elevation profiles for any road or
trail. Flexible tools allow freehand drawing, GPS point conversion, automatic trail
tracing, and customizable symbols. Discover 300,000 miles of trails, including 43 national
park and 120 national forest trail networks. Print 11-by-17-inch maps or tiled
8-by-11-inch mural maps while maintaining map data on your hard drive, letting you
conveniently travel disc-free.
New users will find Topo USA 3.0 easy to install and learn, quickly creating and printing
finely detailed topological maps for hiking or hunting trips. Those familiar with older
versions will thrill to the new automatic trail and road routing, land-cover data that
integrates trees and other
features into maps.
Maps can be ported to Palm-running PDAs and a
wide range of GPS devices--just make sure to bring spare batteries, or, failing that, a
compass. The data is current as of early 2001, including more than 300,000 miles of
trails, from America's deepest trenches to its highest
peaks. Even users who don't spend most of their time outdoors will find the added
dimensions a neat twist to their virtual explorations.
