DESCRIPTION

v.delaunay uses an existing vector points map (input) to create a Delaunay triangulation vector map (output).


Delaunay triangulation example:


Delaunay Triangulation

EXAMPLE

Commands used with the Spearfish dataset to create the above figure. 
  g.region n=4927250 s=4920000 w=588650 e=605850
  v.delaunay -lr in=archsites out=arch_delaunay
  d.vect map=arch_delaunay color=0:0:255
