[Qgis-user] Reasonable size for polygonize

Mon Feb 3 07:48:49 PST 2014

Also, in QuantumGis 1.8 / Grass, I've noticed that some raster functions
(ex: *r.surf.contour)* crash if the resulting raster is a big one (in terms
of pixel size vs ROI); I remember the threshold for crashing was something
like 1.ooox1.ooo lines.
