[Qgis-user] Request help 'Aggregate polygons' QGIS 3

[flavio.taccaliti at libero.it]

Hi everyone,

This is my first message in a users' group, I hope not to break any "netiquette" rule.

I have come across this little problem, and I would like to ask you if there is a simple solution to it:
I am looking for a QGIS 3 tool similar to ArcGIS "Aggregate polygons", http://desktop.arcgis.com/en/arcmap/10.3/tools/cartography-toolbox/aggregate-polygons.htm ( (it takes a multipolygon layer and aggregate the polygons that are closer than a given distance).

I have come across some results on the web, like using PostGIS (https://gis.stackexchange.com/questions/113084/qgis-equivalent-to-arcgis-aggregate-polygons) or
Unfortunately, I have no experience with Postgres or SQL yet, and given the limited amount of time I have for this task it would be unfeasible for me to learn them now.

"Concave hull" tool (https://plugins.qgis.org/plugins/concavehull/) does not what I am looking for, as I would like to set the maximum distance between polygons in the clusters, not the maximum number of polygons.
Also "aggregate" function seems to me not to aggregate polygons by their proximity (https://docs.qgis.org/testing/en/docs/user_manual/processing_algs/qgis/vectorgeometry.html#aggregate).

For the moment I have used the ArcGIS tool on another computer, but the idea is to write down some simple instructions for other users who will have even less expertise than me. Maybe the "button" already exists in QGIS 3, in that case excuse me for the repetition.

Thank you in advance for any suggestion or indication.

Best regards,

FT
