Description
When passing the '-e' flag to r.viewshed.cva, each of the individual, single viewpoint maps gets a value of "invisible = NULL, else current elev-viewpoint_elev". However when the maps are combined using r.series, the result is a count of the maps. So invisible pixels get a value of 0, instead of NULL.
I suggest to use the r.series method=minimum when the '-e' flag is passed so as to keep the elevation difference in the cumulative viewshed output.
Diff attached.
