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
type count min max
point 0 0 0
line 0 0 0
boundary 0 0 0
centroid 38 1 75
area 0 0 0
face 0 0 0
kernel 0 0 0
all 38 1 75
Thanks, Dave
