[GRASS-user] generalize polygons including holes

[Robert Nuske]

Hi GRASS-Users

is there a way to generalize polygons including their holes?
I am not too worried about topology, there are only polygons of one class in 
the dataset. 


I tried the following
v.generalize in=m3 out=m5 type=area method=douglas threshold=5000

which simplified the "outer boundaries" okay but did not touch the "inner 
boundaries"/ holes of the polygon.


Outer boundaries are on the left side in the picture and holes on the right

Suggestions are very welcome.
