<p class="MsoNormal">Dear list,<o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-GB">I am trying to solve the following problem:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I have one polygon layer with many polygons that are in many cases overlapping and with different attribute valus, e.g. a, b, c:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><img width="406" height="387" style="width:4.2291in;height:4.0312in" id="Grafik_x0020_1" src="cid:image001.png@01DCA01D.DFC66850"></span><span lang="EN-GB"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">My goal is to generate a polygon layer with polygons for every overlap constellation containing a concat string of those attributes, in this example seven polygons with the attributes a, b, c, ab, bc, ac, abc.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">I started with a union of my original layer, the result is a layer with 12 polygons where overlapping areas of the original polygons result in overlapping intersections containing one of the original attributes each,
for example in the middle, there are 3 polygons, one with a, one with b and one with c.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">How is it possible to summarize those overlapping polygons into one polygon each with all the attributes, given that there is a large number of polygons and different attributes?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Thank you for any hints,<o:p></o:p></span></p>
