Hi,

you could first add two new columns to the attribute table of your point vector (v.db.addcol) and then
populate them with lat/long (with v.to.db). Afterwards it should be possible to use the query vector map
tool from the map-display window.

if using the UNIX xmons (not the wxGUI), you can use 'd.what.vect -x' and
-t for that. If using the wxGUI you have to cut and paste the results of
the query tool out of the output tab in the layer manager. (select + right
click in the text canvas)
