Hallo If you have your data stored in PostGIS you can do it directly in the database.
To get a new table with the snapped points and the line attribudes you can run: CREATE TABLE line_attribute_point AS SELECT distinct on (linetable.id) linetable.*, ST_ClosestPoint(linetable.geom, pointtable.geom) as snapped_point FROM linetable,pointtable ORDER BY ST_Distance(linetable.geom, pointtable.geom); Something like that. But this will be slow if you have many points and polygons. Then you can use ST_Dwithin to speed it up if you know how far away the line and point can be that should be snapped. Say you don't want to snap longer than 100 meters then: CREATE TABLE line_attribute_point AS SELECT distinct on (linetable.id) linetable.*, ST_ClosestPoint(linetable.geom, pointtable.geom) as snapped_point FROM linetable INNER JOIN pointtable on ST_Dwithin(linetable.geom, pointtable.geom, 100) ORDER BY ST_Distance(linetable.geom, pointtable.geom); Something like that.
