Intersecting some points with polygon features, there are multiple points per polygon. The trouble I'm having is I'd like to have a delimiter separated summary of an attribute from the joined points. As an example, three points might intersect one polygon (they have ID values 1,2 and 3).
The desired output would be polygon geometry with a field called Summary ID and a value of "1;2;3" for that polygon.
Does anyone know of a transformer that might handle this attribute merge?
