     Type:  defect       |      Status:  new                      
 Priority:  normal       |   Milestone:  7.0.0                    
Component:  Raster       |     Version:  svn-trunk                
 Keywords:  r.viewshed   |    Platform:  Unspecified              
      Cpu:  Unspecified  |  
-------------------------+--------------------------------------------------
 The binary flag for r.viewshed makes viewed areas = 1 but unviewed areas =
 null(). Unviewed areas are supposed to be = 0.

 For example:

 {{{

 r.viewshed -b input=elevation at PERMANENT output=a_view
 coordinate=634681,221947
 GRASS 7.0.svn (nc_spm_08):~ > r.info -r a_view
 min=1
 max=1

 }}}
