Question:
Can I create Point objects where my Line layers intersect?
Answer:
Yes - in QGIS, there is the perfect tool for this – called the Line Intersections tool.
In my example below, I have a line layer for the main roads (red) and a line layer for the local roads (brown) and I wish to create a Point layer for the Road Junctions where these lines intersect.
In QGIS choose Processing > Toolbox > and open the Network Overlay section.
Choose the Line Intersections menu option and complete the window below.
- Input layer– choose the Main Road Layer.
- Intersect layer– choose the Local Road Layer.
Press Run and the tool will then calculate any intersection points between the two polyline layers.
The output will be a new Point Layer, with a point object positioned at the each of the line intersections, thus creating a Road Junction Layer.
