A curiosity question. I am looking for making a field calculation with QGIS, I see is possible to include the geometry field of the same feature layer, nevertheless I was wondering if it is possible to use the geometry from other layers features in my calculation. For example, intersection or else.
Should be possible, the
get_feature function enables you to access features from any layer. In combination with the
geometry function you may obtain the features geometry for spatial relationship analyses etc. (
geometry(get_feature())). Key challenge in my opinion is a clever selection of the features depending on the processed dataset:
