Q: In a site map, how to select all the points that are at the edge?
A: Just an idea:
Use v.out.region to create a box (set size with g.region) or use v.hull. Then v.type to change the area to a line. Then v.buffer to buffer it. Then 'v.select op=overlap' (or v.overlay) to fetch the points within the buffer (see GrassSixTutorialFaq#5_Clipping_points)
