GRASS Coverage Prediction Model

I'm sending the source of it. I implemented it in C using the standard
libraries of Grass.
It's still in a 'beta' phase mainly because it doesn't limit the coverage,
it just calculates the path loss prediction from the usual okomura-hata
model extended up to 100 km away from the transmiter. See Etsi Technical
Report 103 and ITU-R Rec. 529 for specifications.

I've done it in Linux and I haven't tested it in another system so I hope it
runs fine.

Good luck

I noticed your posting on the GRASS Programmers Forum on your implementation
of a coverage prediction model.

That sounds like something that might be useful to me.  I'd like to take a
look at it.
