I am replying in an old thread but I've been trying to grab area size per
class from a (CORINE land cover) vector map. Still no luck for a quick and
easy way.
I forgot:
My column with the various land cover classes is "a_code".
So thw question is actually how could I sum up area's based on "a_code"?
Have you tried (using sqlite or postresql as data backend):
v.to.db area
echo "select a_code, sum(area) from CorineTable group by a_code" |
db.execute
