Had a quick look at HFTA

You need some kind of profile of the path you want to examine. I'd
suggest you download 3dem and use its profile output function (draw a
line and it graphs the result and makes an ASCII text file of the
results) You can use SRTM data for input. This will give you 90m odd
horiz resolution.

You'll be able to create an ASCII text file as outlined in the HFTA PDF
manual page 2 - and use that for input.

I cant for the life of me remember the URL for 3dem but I remember you
have to register an email address agaanst it. I dont think any spam was
generated from it. If you get lost gimee a shout and I'll see if I can
legally upload it to you - or I'll find the URL!

Go for it!

Cheers Bob

of bcnntp and you'll get me.
