turf - A modular geospatial engine written in JavaScript
Turf is a JavaScript library for spatial analysis. It includes traditional spatial operations, helper functions for creating GeoJSON data, and data classification and statistics tools. Turf can be added to your website as a client-side plugin, or you can run Turf server-side with Node.js (see below).Download the minified file, and include it in a script tag. This will expose a global variable named turf.

The changelog is automatically generated via standard-version and can be found in project root as well as npm tarball. Please, be noted, no one, I mean, no one, is obligated to help you in ANY means. Your time is valuable, so does our contributors. Don't waste our time posting questions like “how do I do X with React-Google-Maps” and “my code doesn't work”. This is not the primary purpose of the issue tracker. Don't abuse.

The fastest and smallest JavaScript polygon triangulation library. 2.5KB gzipped.The library implements a modified ear slicing algorithm, optimized by z-order curve hashing and extended to handle holes, twisted polygons, degeneracies and self-intersections in a way that doesn't guarantee correctness of triangulation, but attempts to always produce acceptable results for practical data.

A Leaflet-friendly API for point in polygon operations, using substack's point in polygon library.An array of polygons in which the given point resides, an empty array if there are none. The polygons are returned as direct sublayers, so they can include MultiPolygons. You can call pointInLayer again on those if you want the sub-polygon result.
