I have two feature Datasets. Both are Polygons. 'Dataset A' has very big Areas and 'Dataset B' just small ones. Now, 'Dataset B' still overlaps in 2 or 3 Zones from 'Dataset A'.
I want to perform a spatial join and put the result comma separated in just one row like this:
Zone_ID_A | Zone_ID_B 1 | 2,3 2 | 2,4 3 | 5 4 | 1,6
I know this is possible with ArcMap but i could not figure out a way to do this in QGIS, any ideas?
