turf - A modular geospatial engine written in JavaScript

•    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.

turf-intersect - find the intersection of features

•    Javascript

---

Takes two Polygon|polygons and finds their intersection. If they share a border, returns the border; if they don't intersect, returns undefined.Requires nodejs.

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

•    Javascript

---

Takes a pointGrid FeatureCollection of points with z values and an array of value breaks and generates filled contour isobands. These are commonly used to create elevation maps, but can be used for general data interpolation as well.Requires nodejs.

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

•    Javascript

---

This is an example of how to use Turf for a scripting task with node. This technique lets you process bigger amounts of data than you could in a browser, and have node read and write files.Then the npm command with automatically find, download, and install turf to this directory.

turf-server-example - an example of using turf on a server with node.js

•    Javascript

---

Demonstrates using Turfjs in a nodejs expressjs server. Visiting the page will measure your bandwidth, add it to a map, and show a TIN of other people's network speeds.See index.js for the server code and public/index.js for the client-facing code that works with browserify.

turf-union - find the union of geographic features

•    Javascript

---

Takes two Polygon|polygons and returns a combined polygon. If the input polygons are not contiguous, this function returns a MultiPolygon feature.Requires nodejs.

mapbox-java - Mapbox Java and Android Services.

•    Java

---

Mapbox Android Services contains directions, geocoding, and many more APIs to use inside your Android or Java application. This repository holds the source code for the project and is divided into several modules to make it easier for developers to only include the dependencies needed for their project.If you are looking to include this inside your project, please take a look at the detailed instructions found in our docs. If you are interested in building from source, read the contributing guide inside this project.

turf-swift - A Swift language port of Turf.js.

•    Swift

---

A spatial analysis library written in Swift for native iOS, macOS, tvOS, watchOS, and Linux applications, ported from Turf.js.Turf for Swift is experimental and its public API is subject to change. Please use with care and open issues for any problems you see or missing features that should be added.

turf-buffer - Buffers a point, linestring, or polygon Feature/FeatureCollection to a given radius

•    Javascript

---

Calculates a buffer for input features for a given radius. Units supported are miles, kilometers, and degrees.Requires nodejs.

turf-builder - A simple UI for generating custom browserify builds of Turf.js

•    HTML

---

A simple user interface for generating custom browserify builds of Turf.js. This simple app enables users to generate custom browserify builds of Turf.js without the commandline. Simply check the boxes on the interface and hit 'Build' ; this will generate a single javascript file with the relevant modules ready for use in the browser.

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

•    Javascript

---

Calculates the distance between two Point|points in degrees, radians, miles, or kilometers. This uses the Haversine formula to account for global curvature. Requires nodejs.
