[GRASS-user] areas with no centroid

[Dave Roberts]

After editing a map with wxgui I ended up with 39 areas and 38 
centroids.  How do I find and delete the area with no centroid?

I have tried many combinations of v.info, v.category, v.to.db, and 
visualizing with d.vect.  If I use v.clean tool=rmarea with slowly 
increasing thresholds it gets rid of an area I want before it finds the 
one I don't so I don't think it's a sliver.

GRASS GIS 7.3.svn > v.info demo
  . . .
Number of points:       0           Number of centroids: 38 
Number of lines:        0           Number of boundaries: 112
Number of areas:       39           Number of islands:    19
  . . .
GRASS GIS 7.3.svn > v.category demo op=report
Layer/table: 1/demo

kernel         0          0          0
all           38          1         75

Thanks, Dave
