Tesselates a polygon or multipolygon into a collection of triangle polygons using earcut.

Checks if two geometries have no overlapping areas.

Determine whether none of the points common to both geometries intersect the interiors of both geometries.

Takes any number of features and returns a rectangular Polygon that encompasses all vertices.

Takes a collection of points and a bounding box, and returns a collection of Voronoi polygons.

Truncates precision of GeoJSON coordinates.

Takes a polygon and return true or false as to whether it is concave or not.

Checks if the geometry is a valid according to the OGC Simple Feature Specification.

Polygonizes a set of lines that represents edges in a planar graph.

Determine whether two geometries of the same type have identical X,Y coordinate values

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.

Takes a ring and return true or false whether or not the ring is clockwise or counter-clockwise.

Creates a convex hull around points

Calculates the length of a line, perfect for paths or routes.

Takes a kinked polygon and returns a feature collection of polygons that have no kinks.

Calculates the distance along a rhumb line between two points.

Measures the straight-line distance between two points, like cities or landmarks.

Calculates the distance between a given point and the nearest point on a line.

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

Takes any LineString or Polygon GeoJSON and returns the intersecting point(s).
