Concave Hull Generator
Create a concave GeoJSON boundary around location points to represent their footprint more closely than a convex hull.
Input
Hull shape depends strongly on maximum edge length and point distribution; sparse or collinear input may have no valid result.

Understanding Concave Hull Generator
How new geometry is constructed
Create a concave GeoJSON boundary around location points to represent their footprint more closely than a convex hull.
Concave Hull Generator 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
Hull shape depends strongly on maximum edge length and point distribution; sparse or collinear input may have no valid result.
Inspect sparse areas, edges and degenerate inputs in the Concave Hull Generator result. Compare the generated geometry with the source at several zoom levels and keep the original data available.
