NAME

v.hull

DESCRIPTION

v.hull computes the convex hull of a vector points map and outputs the convex hull polygon as a vector area map. The convex hull, or convex envelope, for an object or a set of objects is the minimal convex set containing the given objects. This module creates a vector polygon containing all vector points of the input map.
