gvSIG 1.11 User manual - Analysis and data processing - Vector - Geoprocessing tools - Convex hull - Introduction
This geoprocess calculates the “Convex hull”, or the smallest convex polygon which surrounds all the vector elements in an “input layer”.
It only works with an “input layer” whose geometry type can be any type (point, line or polygon). There are different types of applications for this geoprocess: Determining the coverage area for a specific geographical phenomenon.
Calculating the diameter of the area covered by a series of geometries, etc.
