#3547: r.viewshed.cva with -e flag
----------------------------+-------------------------
Reporter: micha | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: minor | Milestone: 7.4.1
Component: Addons | Version: unspecified
Keywords: r.viewshed.cva | CPU: Unspecified
Platform: All |
----------------------------+-------------------------
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.
