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

•    Javascript

---

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.

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.

Geolib - Growing library to provide some basic geo functions

•    Javascript

---

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).

QGIS - Geographical Information System (GIS)

•    C++

---

QGIS is an Open Source Geographic Information System. QGIS aims to be an easy to use GIS, providing common functions and features. The initial goal was to provide a GIS data viewer. QGIS has reached that point in its evolution and is being used by many for their daily GIS data viewing and editing needs. QGIS supports a number of raster and vector data formats, with new support easily added using the plugin architecture.

react-simple-maps - An svg map component built with and for React

•    Javascript

---

An svg map component built with and for React. It allows the creation of pure react svg maps. React-simple-maps aims to make working with svg maps in react easier. It handles tasks such as panning, zooming and simple rendering optimization, and takes advantage of parts of d3-geo and topojson-client instead of relying on the entire d3 library.

GEOSwift - The Swift Geographic Engine.

•    Swift

---

Easily handle a geographical object model (points, linestrings, polygons etc.) and related topographical operations (intersections, overlapping etc.). A type-safe, MIT-licensed Swift interface to the OSGeo's GEOS library routines, nicely integrated with MapKit and Quicklook. GEOS is a configure/install project licensed under LGPL 2.1: it is difficult to build for iOS and its compatibility with static linking is at least controversial. Use of GEOSwift without dynamic-framework-based CocoaPods and with a project targeting iOS 7, even if possible, is advised against.

Whitebox Geospatial Analysis Tools - An open-source GIS and remote sensing package

•    Java

---

Whitebox GAT is an open-source geographical information system (GIS) and remote sensing package. The Whitebox GAT project began in 2009 and was conceived as a replacement for the Terrain Analysis System (TAS). Whitebox GAT is intended to provide a platform for advanced geospatial data analysis with applications in both environmental research and the geomatics industry more broadly.

leaflet-geosearch - Leaflet geosearching/geocoding control

•    Javascript

---

If you don’t use npm, you may grab the latest UMD build from unpkg (either a development or a production build). The UMD build exports a global called window.GeoSearch if you add it to your page via a <script> tag. We don’t recommend UMD builds for any serious application.

node-maxmind - Maxmind GEO Lookup

•    Javascript

---

Pure Javascript module for Geo IP lookup using Maxmind binary databases (aka mmdb or geoip2). Fastest Maxmind lookup library available - up to 17,000% faster than other libraries. Module has 100% test coverage with comprehensive test suite. It natively works with binary Maxmind database format and doesn't require any "CSV - {specific lib format}" conversions as some other modules do. Maxmind binary databases are highly optimized for size and performance so there's no point working with other than that format. You might want to use geolite2 module with free geo databases. Alternatively, free databases available for download here. If you need better accuracy you should consider buying commercial subscription.

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

•    C++

---

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.

topogram - Continuous area cartograms with d3 and TopoJSON

•    HTML

---

This is a JavaScript implementation of an algoritm to construct continuous area cartograms, by James A. Dougenik, Nicholas R. Chrisman and Duane R. Niemeyer, ©1985 by the Association of American Geographers. It relies heavily on d3 for rendering and TopoJSON both for writing and reading topological JSON geodata. The included example combines TopoJSON-encoded and boundaries of the United States from Natural Earth with 2011 US Census population estimates to size each state proportionally.
