Off-road, where there are no pre-mapped tracks, most hand-held GPS systems show your current coordinates, along with major landmarks like streams and mountains, and keep track of the paths you have followed. They don't tell you what the terrain is like, or what is beyond the next hill or bend.
But the DeLorme Earthmate GPS PN-20 knows, displaying topographical maps — with elevation profiles, campgrounds and trails as well as streets and highways — as realistic 3-D flyover simulations, or as bird's-eye aerial or satellite views showing landmarks.
The DeLorme Topo USA 6.0 DVD software, with topological and road maps of the United States and major-highway maps of the world, is included in the $370 price of the PN-20. Roads can be superimposed on topological maps and aerial imagery downloaded from the Web and stored in a 75-megabyte user memory or optional SD cards up to 2 gigabytes.

Who knows the day may not be far, when topologica input data will be available for SEA too
