Re: [Pymag-devel] Unable to render Polygons

[henrik j. <hen...@gm...>]

Actually they are discarded, they thing is that those warnings are not
from those that make Mapsend crash. I still haven't been able to find
out those that cause the problem. In Ingo's example from Bremen I know
that there are only polygons from parks that cause problems. Far from
all parks though because I can see most of them and they look correct.

Maybe the easiest way is to make a osm file with only those parks and
then try to find the bad ones.
