Is anyone aware of a function equivalent to "Near" in ArcGIS? (see

for reference) I have been searching all day and haven't come across
anything quite like it. It seems like such basic functionality I would
be surprised if someone hasn't already coded a solution.
The GRASS module v.distance should do what you want (available in QGIS's
GRASS toolbox). You'll probably also need the v.db.addcol module to
prepare relevant columns in the first point vector's attrib table for
the feature_id, x, y, dist, etc. of the nearest features in the second
vector.
