geojson-vt - Slice GeoJSON into vector tiles on the fly in the browser

A highly efficient JavaScript library for slicing GeoJSON data into vector tiles on the fly, primarily designed to enable rendering and interacting with large geospatial datasets on the browser side (without a server).Created to power GeoJSON in Mapbox GL JS, but can be useful in other visualization platforms like Leaflet and d3, as well as Node.js server applications.

mapbox-gl-js - Interactive, thoroughly customizable maps in the browser, powered by vector tiles and WebGL

Mapbox GL JS is a JavaScript library for interactive, customizable vector maps on the web. It takes map styles that conform to the Mapbox Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using WebGL.Mapbox GL JS is part of the cross-platform Mapbox GL ecosystem, which also includes compatible native SDKs for applications on Android, iOS, macOS, Qt, and React Native. Mapbox provides building blocks to add location features like maps, search, and navigation into any experience you create. To get started with GL JS or any of our other building blocks, sign up for a Mapbox account.

mapbox-gl-native - Interactive, thoroughly customizable maps in native Android, iOS, macOS, Node

A library for embedding interactive, customizable vector maps into native applications on multiple platforms. It takes stylesheets that conform to the Mapbox Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL. Mapbox GL JS is the WebGL-based counterpart, designed for use on the Web.If your platform or hybrid application framework isn’t listed here, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.

tippecanoe - Build vector tilesets from large collections of GeoJSON features.

Builds vector tilesets from large (or small) collections of GeoJSON, Geobuf, or CSV features, like these.The goal of Tippecanoe is to enable making a scale-independent view of your data, so that at any level from the entire world to a single building, you can see the density and texture of the data rather than a simplification from dropping supposedly unimportant features or clustering or aggregating them.

togeojson - convert KML and GPX to GeoJSON, without the fuss

This converts KML & GPX to GeoJSON, in a browser or with Node.js.Convert a KML document to GeoJSON. The first argument, doc, must be a KML document as an XML DOM - not as a string. You can get this using jQuery's default .ajax function or using a bare XMLHttpRequest with the .response property holding an XML DOM.

MapShaper - Tools for editing Shapefile, GeoJSON, TopoJSON and CSV files

Mapshaper is software for editing Shapefile, GeoJSON, TopoJSON, CSV and several other data formats, written in JavaScript. The mapshaper command line program supports essential map making tasks like simplifying shapes, editing attribute data, clipping, erasing, dissolving, filtering and more.

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.

Geolib - Growing library to provide some basic geo functions

Library to provide basic geospatial operations like distance calculation, conversion of decimal coordinates to sexagesimal and vice versa, etc. Takes 2 or 4 arguments. First 2 arguments must be objects that each have latitude and longitude properties (e.g. {latitude: 52.518611, longitude: 13.408056}). Coordinates can be in sexagesimal or decimal format. 3rd argument is accuracy (in meters). So a calculated distance of 1248 meters with an accuracy of 100 is returned as 1200 (accuracy 10 = 1250 etc.). 4th argument is precision in sub-meters (1 is meter presicion, 2 is decimeters, 3 is centimeters, etc).

Tile38 - Geospatial database, spatial index, and realtime geofence

Tile38 is a in-memory geolocation data store, spatial index, and realtime geofence. It supports a variety of object types including lat/lon points, bounding boxes, XYZ tiles, Geohashes, and GeoJSON. It supports spatial index with search methods such as Nearby, Within, and Intersects, Realtime geofencing through persistent sockets or webhooks and lot more.

geojson-js-utils - JavaScript helper functions for manipulating GeoJSON

Here you will find some functions to help you manipulate and work with GeoJSON objects.You now have an object named gju that contains all of the helper functions.

leaflet-omnivore - universal format parser for Leaflet & Mapbox.js

Leaflet supports the GeoJSON format by default. What if you have something else? That's where omnivore comes in.Omnivore also includes an AJAX library, corslite, so you can specify what you want to add to the map with just a URL.

geobuf - A compact binary encoding for geographic data.

Geobuf is a compact binary encoding for geographic data.Think of this as an attempt to design a simple, modern Shapefile successor that works seamlessly with GeoJSON. Unlike Mapbox Vector Tiles, it aims for lossless compression of datasets — without tiling, projecting coordinates, flattening geometries or stripping properties.

shapefile - A cross-platform streaming parser for the ESRI Shapefile spatial data format.

For a live example, see bl.ocks.org/2dd741099154a4da55a7db31fd96a892. See also ndjson-cli for examples of manipulating GeoJSON using newline-delimited JSON streams. See Command-Line Cartography for a longer introduction. In-browser parsing of dBASE table files requires TextDecoder, part of the Encoding living standard, which is not supported in IE or Safari as of September, 2016. See text-encoding for a browser polyfill.



python-geojson - Python bindings and utilities for GeoJSON

This library implements all the GeoJSON Objects described in The GeoJSON Format Specification. All object keys can also be used as attributes.

Geo-Maps - High Quality GeoJSON maps programmatically generated

The purpose of this project is to programmatically extract maps from open databases like OpenStreetMap providing you with a ready to use GeoJSON map that fits your needs.

node-gdal - Node.js bindings for GDAL (Geospatial Data Abstraction Library)

Read and write raster and vector geospatial datasets straight from Node.js with this native GDAL binding. GDAL 2.0.1 (GEOS 3.4.2, Proj.4 4.8.0) comes bundled, so node-gdal will work straight out of the box. To get started, browse the API Documentation or examples. This binding is a collaboration between Natural Atlas and Mapbox. Its contributors are Brandon Reavis, Brian Reavis, Dane Springmeyer, Zac McCormick, and others.
