Hi All,
I have extracted the centroids of a map with polygons,
but some of the extracted centroids have identical "cat"
numbers. I suspect that those are centroids of multi-
part polygons that share the same attribute table records
in the original input data (a MapInfo file).
I would like to reduce my set of centroids to only one
per "cat" value.
So my question is.
Is there a simple way to remove features with duplicate
"cat" numbers from a GRASS map?
Thanks and best,
Ben
