Understanding Convex Hull
How new geometry is constructed
Create the smallest convex GeoJSON polygon enclosing the supplied points or geometry vertices.
Convex Hull derives new shapes from supplied locations or boundaries. The output reflects an algorithm and its settings rather than a surveyed or administrative boundary.
How to assess the geometry
At least three non-collinear positions are required; concavities are intentionally removed.
Inspect sparse areas, edges and degenerate inputs in the Convex Hull result. Compare the generated geometry with the source at several zoom levels and keep the original data available.
