So.. I tried it now with the planar graph. Unfortunately an error did
occur with my data and the function also returns several overlapping
edges instead one for touching polygons.
However, I could use the LineMerger that was also used in PlanarGraph by
Michael and I get now what I want :)

Hi Stefan,
Did you try the planar graph plugin.
Last time I had such a problem, I created a planar graph from my polygon
layer,
simplified the resulting edge layer
created a new planar graph (or polygonize) from the simplified edges layer.
Otherwise, to create linestrings from linesegments, use
Hei Larry,
mhm.. maybe I could not really express what I want to do.
I have already polygons - and want to derive the common boundary between
two polygon as "one Linestring". So I need to concatenate the pieces
that intersection() does return. Or are you proposing to simply work
with the (out-)
Hi Stefan,
How about com.vividsolutions.jts.operation.polygonize? That seems to be
what it was intended to do.

Hei,
Today I started some work on analysing and later generalising (i.e.
simplification) of polygon layers where the polygons form a mosaic
(tesselation). So any operation on the boundaries requires that
topologic neighbourhood must be observed. I.e. to simplify an outline I
need to simplify t
