intersectionoverlapping-featuresqgis
I have two overlapping layers of polygons, and I need to somehow erase the areas the overlaps. -This way i should end up with two layers of non overlapping polygons. Sounds pretty simple but I just can't get it right with any of the tools in Qgis!?
Should i use "clip" or "cut shape by polygons", or perhaps the "difference" tool and the "clip"?
Whatever I do the product isn't right.
I would recommend using the Count Overlapping Features (Analysis) tool.
Generates planarized overlapping features from the input features. The count of overlapping features is written to the output features.
After running your Union, open the resultant Attribute Table and I think you will see that all polygons of overlap have IDs from both input feature classes that are >= 1 whereas where there is no overlap one or other ID will be 0.

using qgis 2.0.1. created two overlapping polygons (yellow & green). clip tool creates "difference area" (red polygon). apply difference tool; input vector layer = original polygon layer, difference layer = clip polygon.
results of applying clip polygon with difference tool to each of the original polygons.
hope this helps:)
