It would be nice to be able to choose one or more canyons to display as well
as select feet vs. meters vs. miles, etc.
I could probably do this now with a cgi-bin script if you let me put windows
up on your display (i.e. run gnuplot
with output to the client display).
What I would really like to have are three-dimensional graphs of
latitude, longitude and elevation.
This is one of the reasons I switched to
gnuplot.
However, the prospect of gathering this information from topo maps is daunting.
One thing I am considering is looking into the wealth of data available from the
USGS
in particular the
US GeoData currently available by FTP.
Combining that with current
GIS software
offers interesting opportunities for wasting enormous amounts of time.
Of course, what I really want is an Avocet 1000000 cyclometer with builtin GPS that will automatically sample and relay the data back to my workstation...
