I have a polygon-shape in qgis-1.7.0 and want to fix overlays and gaps between the edges of adjacent polygons. See image below.

enter image description here

Is there any automated way to do this in quantum-gis? Or any other F/OSS that can do things like that?

Any hints appreciated! Thanks!

check out this video Vector topology cleaning with QGIS and GRASS.it uses GRASS Toolbox v.clean which @artwork21 has mentioned.

This video shows how to resolve a few common vector topology problems using GRASS tools of the category "v.clean" through the Quantum GIS interface.

i hope it helps you...

Import your vectors into GRASS (GRASS should be included in QGIS install) and use the v.clean module. That should clean your topology errors.
