I have searched the manuals, and have not found a direct tool. The objective would be to output unique point ID’s with corresponding elevations. Is there a tool which would provide for one to attach raster (elevation) values to vector points?
If no tool, would this be the most efficient approach?
points to raster (all others null).
r.mapcalc to assign elevation raster values to converted raster cells.
convert raster cells to polygons.
overlay polygon (elevation) values onto original points.

open Source Support is always the fastest!
imagine: Caling the ESRI support, get a ticket - ... - next day 1.
answer: we received your requst - ... - one week later got a 2. response
- answer: wait for next release, ...
this is not fiction!
