<p>Hallo Leute,</p>
<p style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">bei der aktuellen Version 2.18.20 habe ich häufiger das problem, dass beim Verschnitt zweier Shapes folgende Fehlermeldung erscheint:
<span style="color:#ff0000">
GEOS-Verarbeitungsfehler: Ein oder mehrere Eingabeobjekte haben ungültige Geometrien.</span>
</p>
<p style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">
</p>
<p style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">Auch nach intensiver Überprüfung konnten keine Geometriefehler gefunden werden. Wäre auch ungewöhnlich, da die selben Geometrien in allen vorherigen QGIS-Versionen in den letzten drei Jahren immer reibungslos verschnitten werden konnten...</p>
<p style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">
</p>
<p style="margin-top:0px;margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">Könnt ihr mir helfen?</p>
