I have a schematic diagram within QGIS consisting of a single layer of line segments. Lines have been snapped to others using "snap to segment". When using the snap to segment option the two lines that intersect do not share a common vertex.
I am attempting to use Road Graph to navigate the schematic, find paths and distances. The issue is that the shortest path algorithm requires two lines that share a common point.
Is there a plugin, script, or otherwise known procedure to add a common vertex/point on two lines that have been snapped using "snap to segment"?
