I'd like to know how a vector layer can take and aggregate attributes of a field, of another vector layer which is overlapped.
For example, a layer T1 has not overlapped records while on the contrary the layer T2 could have overlapped records. I should have a "NEW" field in T1 with the data of T2, separated with ';' every time T2 records overlaps on T1.
How do I automate this process using QGIS?
