Dear listers,
I was wondering if anyone could update me on the current state
of viewshed analysis within GRASS? I have heard that the
standard module r.los truncates viewer height to the nearest
integer value. This is also borne out by my own use of it.
There is also Mark Lake's r.cva module, which solves the
viewer height problem, but as far as I understand this module
has not been fully updated to the GRASS 5.x environment and
treats floating point DEMs as integer maps.
Are there any plans to fix r.los so we at least have a basic
working viewshed analysis module in GRASS?
thanks
Steve
