Friends,
I have an vector area map with numerous polygons with centroids. When I do
v.what.rast vector=A raster=B column=C
It appears to run, but doesn't actually enter any data into column C in
the associated table in Postgres. Reading the help file, I suspect this
is because A is an area instead of a point map, but the areas do have
centroids which I would expect v.what.rast to employ.
I could import the centroids as a separate points map, but then they're
not associated with the table in Postgres.
What's considered best practices in associating polygon centroids with
other rasters or vector areas?
Thanks, Dave
