## DESCRIPTION

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

Delaunay triangulation example (red-yellow points are the data points from which the triangulation was generated):

## EXAMPLE

Commands used with the North Carolina dataset to create the above figure (subset shown in figure).

    g.region n=220750 s=219950 w=638300 e=639000 -p
    v.delaunay input=elev_lid792_randpts output=elev_lid792_randpts_delaunay
