<ul></ul><p>I can reproduce the issue computing the difference of regions and lakes in our QGIS Alaska sample data. (Difference between regions and builtups seems fine though.)</p> QGIS Application - Bug report #13067: The difference tool gives broken results in both 2.10 and 2.11https://issues.qgis.org/issues/13067?journal_id=627602015-07-03T00:04:56ZGiovanni Manghigiovanni.manghi@gmail.com
<ul><li><strong>Target version</strong> changed from <i>Version 2.12</i> to <i>Future Release - High Priority</i></li><li><strong>Priority</strong> changed from <i>High</i> to <i>Severe/Regression</i></li></ul><p>This is the second (basic) vector geoprocessing tool we at the moment see also <a class="issue tracker-1 status-5 priority-5 priority- closed" href="https://issues.qgis.org/issues/11986" title="Intersection returns the wrong result (Closed)">#11986</a> (not to speak about how slow they all are).</p>
<p>I really think that this tools should be really fixed once for all as any gis user expect them to work and having to say "don't use the intersection/difference/whatever tool is kind of embarrassing. It even could be dangerous... what about if I take for good the result of one of this operations and then give wrong results that have a real world (legal for example) impact?</p>
<p>Now that we have the routine to create virtual vectors I plan at some point to add the same basic tools based only ogr/sql/geos (there are already a few in Processing).</p> QGIS Application - Bug report #13067: The difference tool gives broken results in both 2.10 and 2.11https://issues.qgis.org/issues/13067?journal_id=627652015-07-03T05:02:05ZEtienne Trimailleetienne.trimaille@gmail.com
