Convex Hull

This node generate the smallest convex Polygon containing all the points in each geometry. The convex hull of a geometry is the smallest convex Polygon containing all the points in each geometry, unless the number of points in the geometric object is less than three. For two points, the convex hull collapses to a LineString; for 1, a Point.

The node is based on the GeoPandas project and uses the following related information and function:

• Convex hull

Input ports

1. Type: Table
   Geo table

   Input table with a geospatial column to compute the 'hull' for.

Output ports

1. Type: Table
   Geo table with hull

   Geo input table with additional 'hull' column containing the hull of each input geometry in the units of the CRS.
