I'm working with QGIS 2.18

In a print composer I can filter the elements of a layer based on the attribute of the active element of an atlas. For example, show only the cities (points) of a state (polygons), when the state layer is the coverage layer of the atlas. I'm using rule-based symbolization, where both layers have a common attribute.

I would like to know if they can be filtered in the same way, but using geometry functions like the intersect. I would like to filter the elements of a layer, which intersect with the elements of the active element of the coverage layer of an atlas.

I'm trying with the intersects function, but I can not get the correct syntax.

Is it possible to make this query?

  • I'm sorry, I find the solution. intersects( transform( $geometry, 25829, 25830) , geometry( @atlas_feature ) ) . In my problem I need to transform the SRC. Commented Aug 5, 2018 at 7:49

This code should be the correct answer to your question:

[% aggregate('LAYER_NAME','concatenate',"ATTRIBUTE", within($geometry,@atlas_geometry), ',') %]

  • if you only need the filter term within($geometry,@atlas_geometry) will do the trick.
