I have been using Delorme Topo USA for years, both when I was in Wyoming and
here in Oklahoma. (I never could figure out how to make MicroDEM play. Too
many interlocking downloads, I guess.)
In Topo, you can set your QTH and then draw a radial toward a point of
interest such as EU. Then you can get a plot of the terrain in that
direction. The resolution is really, really fine. This sure beats the
daylights out of using a USGS topo map and a ruler to work out the contours.
Beyond a certain point, Topo gives distances in miles, so I set up an Excel
spreadsheet to convert to feet. (I could have used meters, I know.) Then I
copied the Excel data and pasted it in a Notebook file that I saved with the
extension .pro.
Beware: HFTA is addictive. ;-)

Friends
I would like to use MicroDEM/HFTA to do some analysis of my site.
Have any of you used Delorme Topo USA to do this, and if so with what
success??
