Checks if a point lies directly on a line, like a path or road.

Finds the central point of a GeoJSON feature, like a city or a park. Ideal for placing labels or markers.

Simple, filesystem-backed memoisation cache.

Takes a Feature or FeatureCollection and returns a Point guaranteed to be on the surface of the feature.

ECC JS code based on JSBN

Low-level network interception library for Node.js.

Takes a Feature or FeatureCollection and returns the mean center.

Takes a triangular plane as a polygon and a point within that triangle, and returns the z-value at that point.

Creates a concave hull around points.

Takes two points and calculates a point midway between them geodesically.

Takes a set of points and partition them into clusters according to DBSCAN's data clustering algorithm.

Calculates the destination point having travelled the given distance along a Rhumb line.

read and write binary structures and data types

Lightweight utility for input validation and data extraction in Turf.js. Ensures GeoJSON inputs are in the correct format and extracts specific components like coordinates or geometries.

Fast robust predicates for computational geometry

Finds the tangents of a polygon from a point.

Creates an interpolated grid of points using the Inverse Distance Weighting method.

Fast nd point clustering.

Useful for extracting only the part of a route between waypoints.
