[Qgis-user] Nearest point on line

[Andrew McAninch]

You can do this in the field calculator with the refFunctions plugin.   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:

closest_point(geom_from_wkt(geomdistance('lines','$geometry',10)) , $geometry)
