<ul></ul><p>Also:</p>
<blockquote>
<p>(c) Difference: Overlay layers such that output contains areas not intersecting the clip layer.</p>
</blockquote>
<p>The output of this is the opposite of the output of (a) and (b). <br />When I read the description I think it is saying this is supposed to be the opposite of (a). If my argument (1) is correct it should be reworded to make it clear that this is the opposite of the "clip" tool, not the opposite of the "intersect" tool.</p> QGIS Application - Feature request #6445: Better documentation for the Intersect and Clip toolshttps://issues.qgis.org/issues/6445?journal_id=354912012-10-03T01:57:02ZGiovanni Manghigiovanni.manghi@gmail.com

Anyway I will have a look to your notes during the developer meeting, but right now I don't see anything particularly wrong about those operations. At least from the geometries point of view they should behave the same as in other gis packages.</p> QGIS Application - Feature request #6445: Better documentation for the Intersect and Clip toolshttps://issues.qgis.org/issues/6445?journal_id=354952012-10-03T03:05:53ZAlister Hood

<p>But surely there shouldn't be two different tools that do exactly the same thing, should there? That's the main reason I filed it as a ticket.</p> QGIS Application - Feature request #6445: Better documentation for the Intersect and Clip toolshttps://issues.qgis.org/issues/6445?journal_id=354962012-10-03T03:15:27ZAlister Hood
<ul></ul><p>Ah, I see.</p> QGIS Application - Feature request #6445: Better documentation for the Intersect and Clip toolshttps://issues.qgis.org/issues/6445?journal_id=354972012-10-03T03:23:56ZAlister Hood
<ul><li><strong>Category</strong> changed from <i>44</i> to <i>Documentation and Help</i></li></ul><p>Intersect and Clip <em>do</em> do different things, but my data wasn't suitable to demonstrate the difference.</p>
<p><em>Clip</em> trims each feature in the input layer so that only the area which overlaps with any feature in the clip layer is left.</p>
<p>When a feature in the input layer overlaps more than one feature in the intersect layer, <em>Intersect</em> also splits it into separate features. I'll try to come up with a better description of the Intersect tool for the documentation, but I need to sleep now :)</p> QGIS Application - Feature request #6445: Better documentation for the Intersect and Clip toolshttps://issues.qgis.org/issues/6445?journal_id=354982012-10-03T03:32:25ZAlister Hood

<p>Of course, to do this you would actually use "Vector>Research tools>Select by location" (and then save the selection as a new file if that's what you need).<br />And you can also do the opposite with the same tool, by first selecting all the features in the layer, and using the option to remove the matching features from the selection.</p> QGIS Application - Feature request #6445: Better documentation for the Intersect and Clip toolshttps://issues.qgis.org/issues/6445?journal_id=355012012-10-03T10:44:58ZGiovanni Manghigiovanni.manghi@gmail.com

<p>I think something like this:</p>
<blockquote>
<p>Intersect: split features in input layer by using features in intersect layer as cutters.</p>
