[GRASS-user] areas with islands and v.generalize

[Georg Kaspar]

Hi everyone,

i'm trying to use v.generalize to smoothen polygon areas generated by
r.to.vect.

when using

v.generalize in=cold out=cold_smooth method=douglas type=area thresh=0.1

the result remains the same as the input geometry.
Leaving out "type=area" leads to smoothened results though islands
become polygons.

v.generalize in=cold out=cold_smooth method=snakes

stops at 62%...

any ideas how to solve this problem?

thanks & best regards,
Georg
