I am having problems with r.viewshed.cva in GRASS GIS 7.0.3 and 7.0.4. I run the addon with the DEM and 100 random vector points as input. The vector points are composed by the cat, and X and Y colum with coordinates. Finally I get this error:
Traceback (most recent call last): File "C:\Users\AppData\Roaming\GRASS7\addons/script s/r.viewshed.cva.py", line 174, in main() File "C:\Users\AppData\Roaming\GRASS7\addons/script s/r.viewshed.cva.py", line 140, in main if flags['k'] and options["name_col"] is not '': KeyError: 'name_col'
My laptop is a Core i7, Windows 10.
