Here is an example of using GRASS for line of sight mapping

By a high school student, no less.

Much of the on-line use of GRASS has been related to wifi mapping.

The only problem I had with it was trying to run it under X64. I works
under XP and win2k.

I've got old XP.


Sometimes if the program is written under later versions of VB (which I
don't know for a fact regarding this program), the DLLs are not
present. [This happens with X64.] The older versions of VB created
larger files, but were less dependent on the OS being stuffed with the
right DLLs.

If the complaint is missing files, google the name of those files. If

It doesn't give any file names.

I think I will contact the company.

you find them, place them in the same directory as the install program.
This will get the program working at least once. At that point, you
need to do the research to see where exactly the DLLs normally reside.
Any chance you are using windows ME (the minus edition)?

If you could write up how to install Octave with cygwin, I'd appreciate

It's been a long time since I installed it.
I installed version 2.1.36. Looks like 2.1.72 is the current best.
During the install I believe I referred to the following:

it. I was trying to run GRASS, another linux program, with cygwin, and
had no luck. Grass can compute line of sight regions using USGS
seamless files. It's not really useful for HF, but it is useful for VHF
on up.

Interesting.
