turf ORG

A modular geospatial engine written in JavaScript and TypeScript

A modular JavaScript library that brings GIS mapping analysis, distance, area, intersection, clustering, directly into browser or Node.js apps using standard GeoJSON data.

an example of how to use Turf for a scripting task with node.

[DEPRECATED] an example of using turf on a server with node.js

Checks to see if a point is inside of a polygon.

Calculates the distance between two point features in degrees, radians, miles, or kilometers.

find the intersection of features

A collection of awesome projects in the turfjs ecosystem

Buffers a point, linestring, or polygon Feature/FeatureCollection to a given radius. Units supported are miles, kilometers, and degrees.

Examples of Turfjs visualized with mapbox.js

Takes a FeatureCollection of points with z values and an array of value breaks and generates filled contour isobands.

find the union of geographic features

Transforms a LineString geometry to a (closed) Polygon geometry.

Cut a polygon with a polyline

Clips a Feature by a bbox

A minimal subset of JSTS features bundled and compiled to ES5

Segment a LineString by Features

Makes outer rings cw, inner rings ccw. Or reversed

Takes a bounding box and a cell depth and outputs a feature collection of points in a grid.

Create voronoi polygons from a set of points

Takes a set of overlapping polygons and returns non overlapping donuts.

Get Voronoi cells constrained to a Polygon

Gets the Pole of Inaccessibility of the input polygon

Vincenty's inverse formula computes the geographical distance and direction between two given points.

Vincenty's direct formula computes the location of a point which is a given distance and direction from another point.

Divide a linestring into segments of specified length
