[Qgis-user] Qgis atlas print composer : aggregate (bigger overlap)

[celati Laurent]

Good afternoon,
With Qgis 3.30, In the composer interface, I generate an atlas.
My iteration layer is a polygonal layer (platforms). I added a text element
to automatically get by spatial intersection the 'parcel_id' attribute
present in another polygonal layer. I use the aggregate function for this
task :




*  aggregate('LAYER':="PARCEL_LAYER',aggregate:='concatenate',
expression:="parcel_id",filter:=intersects(geometry(@parent), $geometry))*

It works. But the result shows values of all the intersections. I would
like it limit to the result of the biggest intersection. Would you know how
to do it?

Thanks a lot.
