[Qgis-user] Nearest point on line

[Christoph Jung]

Thank you all for your answers. I played a bit with the nnjoins plugin, but Andrews‘ answer is exactly what I was looking for :)

Sincerely,
Christoph

It gives you a function, geomnearest(), which will return the WKT geometry of the nearest line(or geomdistance() if you want to limit your search radius).  Then use the closest_point() function to find the nearest point on that line.  something like:
