Hi, John–
I was thinking topo maps are _relatively_ wide in appeal, compared to, say,
geological maps. Hikers may not be a majority, but are a large enough group to
rate attention of the CD map sellers after they have handled the drivers.
Hikers who use CDs must be a small group as yet, but must be a very
fast-growing group. The market for CDs in general seems to be exploding, and
sellers who wait for sufficient numbers of customers to be CD-ready will be too
late when competitors can so easily see it in advance.
I read that Encyclopedia Britannica got itself in financial hot water because
they were slow making the turn into CDs – as best I remember, this was before I
was aware that CDs had "arrived", before they suddenly materialized in a big
rack of their own at Sam's Club.
If having E-maps with detailed elevation info can help a GPS-using program to
refine its position estimates (a wild guess), that kind of info could even
become useful to everyone (though they may not know it is in there).
