How can I query polygon features that intersect other polygon features in QGIS? I have ZIP code areas and city areas, and I would like to list all the ZIP codes that intersect the city areas. Example: San Antonio= 78209,78258,78259,78250, etc.
I've been looking for a method for a while that can do this in QGIS, I tried "list unique values and union" commands in the vector tools and no luck. I know you can do a Union in ArcMap Pro but I don't have that software here. I was also able to do this in GeoMedia Pro years ago. I am unable to figure out in QGIS how to do some polygon vs polygon analysis.
I am still having problems with this, I was able to create an intersection layer but I can't figure out how to associate the results back to the city area feature. I would like to add a field to City_Area which would list the ZIP Code names separated by comma. (City_A=78205,78204,78203,78201)
