<p>Hi,</p>
<p>you can use overlay functions instead, there you can sort the
size of intersection and take the biggest one:</p>
<p><i>overlay_intersects(layer:='</i><i>PARCEL_LAYER</i><i>',
expression:="parcel_id", sort_by_intersection_size:='des')[0]</i><br>
</p>
<div>hope this helps</div>

<div dir="ltr">Good afternoon,<br>
With Qgis 3.30, In the composer interface, I generate an atlas.
<div>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 :<br>
<br>
<i> aggregate(<br>
'LAYER':="PARCEL_LAYER',aggregate:='concatenate',<br>
expression:="parcel_id",<br>
filter:=intersects(geometry(@parent), $geometry))</i></div>
<div><br>
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?<br>
</div>

<div>Thanks a lot.</div>
