Extensions for JTS ToplogySuite

This project provides a simple API built with FastAPI that takes a list of 2D points and generates a concave hull (alpha shape) based on a given alpha value. The API returns the coordinates of the shape's edges, which is useful for creating boundary shapes around scattered points.

Python package to retrieve and correctly reshape the polygon of a geographical area.

Concave hull by distance

uhull is a Python package that provides a new algorithm for obtaining the concave hull of 2D point sets. The algorithm works exceptionally well with 'disconnected' sets and outlier points.
