I guess implementing topology rules and visualizing the existing errors would be a way to identify and correct problems like polygon overlaping.<br><br>It might already exist some code.<br><br><a href="http://www.osgeo.org/pipermail/qgis-developer/2010-January/009011.html">http://www.osgeo.org/pipermail/qgis-developer/2010-January/009011.html</a><br>
