Snap Geometry to Layer (Line to Point) does not snap all lines within the tolerance limit

Geographic Information Systems Asked by leighmedy on January 12, 2021

I’ve been using QGIS 3.14 version to snap geometries to layer.

Parameters: Tolerance is 0.6m and behaviour: prefer aligning nodes, insert extra vertices where required

When I try to run this, I have to fix the geometry first before I run select by location.

I checked the output, most are correct but there are lines that did not snap correctly within the tolerance limit I set like this: (The distance in the photo is not even 0.001)

enter image description here

Is the manual way the only way to fix this?

One Answer

The snapping is only done relative to the original line: enter image description here enter image description here This snapping is set to 0.220 meters and as you can see some points are really close to the snapped line but more than 0.220 meters away from the original line so the line doesn't snap to them.
