But I can work with black "lines" shapefile of polygon or polyline depending on what is needed for the query to work. | |

selection is empty with st_intersection. If it can help, blacklines can be polygons since they are closed.

| Jul 27, 2020 at 11:52 | comment | added | Taras♦ | Are they also lines, I mean those yellows? | |
| Jul 27, 2020 at 11:47 | comment | added | Leehan | All lines are selected, not only the yellow ones. But it may be a good start. | |
