There is also the "Join attributes by nearest" in the toolbox.

As it is not clear how your data looks alike, its hard to guess the
right approach.

  <pre class="moz-quote-pre" wrap="">Hi,
I have a road network that is surveyed for road distress.
The network is a line vector layer.
I also have a point layer representing the driven trajectories of the survey
vehicle.
I am looking for a method to update a field of the network layer when [some]
points of the trajectory are "near" the line.
As the trajectory is quite precise, the distances between lines and points are
small and there are no obvious outliers.
What I don't have is the algorithm how to classify the lines if the points of
the trajectory are near the line.
Any help appreiciated!
Roland
