Hello everyone !
I have this problem since a couple of days... I want to aggregate the geometry of several non-touching polygons based on a common attribute (the id of the administrative area they are part of) but I also need to keep the other attributes of each polygon. I thought the Aggregator was the designed tool for that but I can't find out how to keep attributes of each part of the resulting "multipolygon". I always loose information of the individual polygons...
Thanks for your help !
ps: please forgive my english as it's not my mother tongue.
