[gdal-dev] How to use gdal_polygonize.py

[Paul Meems]

Thanks Ari,

Travis mailed me the same info.
I understand better now.
I'm using the data from
http://www.fao.org/geonetwork/srv/en/metadata.show?id=37139&currTab=distributionnow
to test and it is much more clear.

Here in The Netherlands we mostly have land classification already in
vector, that's why I didn't think of that.

Thanks,

Paul
