[GRASS-user] polygons and centroids redux

[Dave Roberts]

Friends,

      This is the second time in two days I have had to post an apology 
and retraction for hasty questions.  I apologize for testing everyone's 
patience.  Thanks Markus; I was composing this message when I saw your 
post.  I mistook a centroid of a polygon too small to plot at the 
current resolution as the centroid of the surrounding hollow area.  My 
mistake; sorry.

     It does raise a question, however, of what the conditions are that 
cause d.what.vect to return a feature type of "Boundary" rather than 
"Area" when querying a map.  Is it simply proximity to the boundary, and 
can that behavior be suppressed in preference to always returning the 
data associated with the centroid?

Thanks, Dave
