All of that is already in place and working. (Well, I don't know if
curvature is working - all the data I have here is in the wrong projection
to work with curvature, but i ported the code from r.los, so hopefully it
should work as expected) Right now, I'm having some issues with it

Sorry for the late reply to this -- too caught up in other things
at the moment.
Earth curvature correction and other generic issues involved in LOS
application design are detailed nicely here:

The article talks about using an approximation in

That's great! I'm sure I can s
