If you want "average voter appeal," I don't think topo maps are high on their
list of wants. I don't think most people coul identify a topo map as a topo
map if it were sitting on the table in front of them.
An electronic topo map is even more obscure. As for a product with topo maps
on CD, I'd venture that topo maps are much more dense than the De Lorme-style
road maps. I believe these DeLorme maps are derived from "DLG" digital line
graph data, also from the USGS, although they may include some topo map info,
too. It may be tough to stick more than a few states in 1:150L topo form on a
single CD. CDROMs may hold four times as much info in a few years, though,
which would change the situation.
