Remove vertices coincident with a point layer
Geographic Information Systems Asked by Noe on December 9, 2020
Is there any way to delete vertices from a feature which are coincident with a point layer? I mean in an automatic way.
I have many lines forming a “T shape”, so I would like to remove the middle vertex of the horizontal line so the only vertex there is the first (or last) one from the vertical line. Every line has a different lenght, so it’s not possible to smooth or simplify the feature.
I have to do it with QGIS (but if there is a way with another software, i would also appreciate the answer).
One Answer
How about using Geometry by Expression tool?
An expression like make_line( start_point($geometry), end_point($geometry)) will ignore the middle vertex.
