Bug report #11986

Updated by Alexander Bruy about 3 years ago

This error happens when intersecting a layer prepared with dissolve. The resulting layer contains only intersections from the last shape of the dissolved layer (with all shapes of the other layer).



For example, I am starting with layers A and B. Layer A includes 1334 shapes, all of them having ids in the attribute table with values ranging from 1 to 3. Layer B includes 7 shapes. I am trying to create the layer BD.



1. Dissolve A to produce D (includes only 3 multi-polygon shapes with ids ranging from 1 to 3).

2. Intersect B with D.



The resulting BD does not include intersections corresponding to D shapes with ids 1 and 2.
