[GRASS-user] possible r.viewshed documentation error?

[G. Allegri]

I think there's an error in the docs of the r.viewshed addon. It states
that the default output raster contains vertical angle relative to the
observer and that the values are:

"a value in [0, 180] representing the vertical angle with regard to the
viewpoint, in degrees, if the point is visible. 0 degrees: directly above
the observer, 180 degrees: directly below the observer" [1]

It's the opposite of r.los, where 0 is below and 180 right above.
The resulting maps are equivalent, and looking to my results r.los
interpretion is right.
