I've just used r.los for the first time, but want to do something slightly different this time. Instead of finding what points on-the-ground are visible by the observer, I want to find what points at a height above-the-ground are visible by the observer. Or the inverse, given a height of an object (person, tree, whatever), what areas could hide these objects. I'm guessing I can't make r.los do what I want without modifying the code.
Just to be clear, the results I'm looking for will indicate a spot is visible even behind a hill, so long as the object height is sufficiently large enough to appear above the top of the hill. Does anyone know of a trick to do what I want, or perhaps have done something similar and can share a script?
