[GRASS5] intersections of radiotracking beams - m.cogo?

Hi,

for a project we want to intersect beams from radiotracking
of animals. I was thinking of m.cogo, but the web page from
Eric Miller doesn't exist any more.

- does anyone have a copy of m.cogo source code?

We also want to include constraints such "viewsheds" for the
radio beam etc. Maybe there is something even better.

Thanks in advance,

Markus

The "Wayback Machine" seems to have m.cogo at

Do you mean the intersection of radio beams or projected directional
track?

You might try a slight modification of r.transect to have it output
end points. (grab the CVS version, it's broken in 5.0.2)

We also want to include constraints such "viewsheds" for the
radio beam etc. Maybe there is something even better.

You might try r.los with max_dist= or r.cva. I've also got a version of
r.los I modified to return azimuth instead of elevation if that is of
any use to you. Note r.los is highly inefficient for larger rasters.
