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.

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

•    MPL

---

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.

Leaflet.AnimatedMarker - A Leaflet plugin to animated a Marker along a polyline

•    CSS

---

It uses CSS3 animations to move the marker from point to point at a specific rate (meter per millisecond). For ancient browsers that don't support CSS3, the polyline is chunked into distance segments and moved per interval (not so great). The following code will create an AnimatedMarker that moves along line, assuming a Leaflet.Map called map.

umap - uMap lets you create maps with OpenStreetMap layers in a minute and embed them in your site.

•    Javascript

---

uMap lets you create maps with OpenStreetMap layers in a minute and embed them in your site. Because we think that the more OSM will be used, the more OSM will be ''cured''. It uses django-leaflet-storage and Leaflet.Storage, built on top of Django and Leaflet. See developer documentation.

tangram - WebGL map rendering engine for creative cartography

•    Javascript

---

Tangram is a JavaScript library for rendering 2D & 3D maps live in a web browser with WebGL. It is tuned for OpenStreetMap but supports any source of GeoJSON/TopoJSON or binary vector data, including tilesets and single files. Here's a simple demo (repo here) with a basic example of a Tangram map.

mapbox.js - Mapbox JavaScript API, a Leaflet Plugin

•    HTML

---

This is the Mapbox Javascript API, version 2.x. It's built as a Leaflet plugin. You can read about its launch.The mapbox.js file includes the Leaflet library. Alternatively, you can use mapbox.standalone.js, which does not include Leaflet (you will have to provide it yourself).

topojson - An extension of GeoJSON that encodes topology! 🌐

•    Javascript

---

TopoJSON is an extension of GeoJSON that encodes topology. Rather than representing geometries discretely, geometries in TopoJSON files are stitched together from shared line segments called arcs. This technique is similar to Matt Bloch’s MapShaper and the Arc/Info Export format, .e00. TopoJSON eliminates redundancy, allowing related geometries to be stored efficiently in the same file. For example, the shared boundary between California and Nevada is represented only once, rather than being duplicated for both states. A single TopoJSON file can contain multiple feature collections without duplication, such as states and counties. Or, a TopoJSON file can efficiently represent both polygons (for fill) and boundaries (for stroke) as two feature collections that share the same arc mesh. See How To Infer Topology for a visual explanation of how TopoJSON works. See Command-Line Cartography for an introduction to TopoJSON and related tools. See TopoJSON Format Specification for the format specification.

Cesium - An open-source JavaScript library for world-class 3D globes and maps

•    Javascript

---

CesiumJS is a JavaScript library for creating 3D globes and 2D maps in a web browser without a plugin. It uses WebGL for hardware-accelerated graphics, and is cross-platform, cross-browser, and tuned for dynamic-data visualization.

leaflet - R Interface to Leaflet Maps

•    Javascript

---

Leaflet is an open-source JavaScript library for interactive maps. This R package makes it easy to create Leaflet maps from R. In addition to the usual R package documentation, we also have extensive docs and examples at: http://rstudio.github.io/leaflet You may use Github issues to file bug reports or feature requests, and ask questions on StackOverflow or in the Shiny mailing list.

esri2open - this repo is an ESRI toolbox and tool(s) that export ESRI Feature Classes to open data formats, CSV, JSON, and GeoJSON

•    Python

---

This repo is an ESRI toolbox and tool(s) that exports ESRI Feature Classes to open data formats, CSV, JSON, SQLite, and GeoJSON. Much of the data in government coffers is contained in spatial databases. A large percentage of government spatial data is created and managed using ESRI software. While the common interchange format, the ESRI Shapefile, is easily exported and imported by many other softwares, this data file format (the Shapefile) is not intrinsically part of the www ecology. Moreover, ESRI software does not provide an export of its generic 'feature class' (shapefile, file geodatabase, and personal geodatabase) to the most common open data file formats, CSV, JSON, and/or GeoJSON. Finally while open source tools easily transform ESRI shapefiles to open data, most government geospatial infrastructures only have ESRI tools. Lacking this basic export feature presented here, means the lion's share of government spatial data users cannot export their data to the most common open data formats.

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

•    Javascript

---

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.

ui-leaflet - AngularJS directive to embed an interact with maps managed by Leaflet library

•    Javascript

---

While we are grateful for all the original work at tombatossals/angular-leaflet-directive. We need to be able to operate as an organization to respond to issues, pull-requests and other various items quicker. We need to be able to add other developers as admins easier via group permissions via github orgs. Lastly this project needs to be more credible via being a group / org.Please note the master branch is currently in a "in-progress state" and is not suitable for use at this point. We are trying break up the library to be more unix / plugin like. This will reduce the burden of constant changes to the core repo (this repo) for each and every unforseeable plugin that leaflet has. Therefore, the new usage plugins will require developers (angular-ui or not) to create specific angular directives, services, factories, and etc to extend the main ui-leaflet directive. Where ui-leaflet would be the main dependency.

geojson-google-maps - A simple utility to convert GeoJSON objects to Google Maps vector objects (Marker, Polyline, Polygon)

•    Javascript

---

Google Maps now has proper support for GeoJSON, so you should probably use that instead. GeoJSON is used to create Google Maps API v3 vectors (Marker, Polyline, Polygon) from GeoJSON objects (Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, Feature, GeometryCollection, FeatureCollection). Specifically, I'm translating some GeoJSON types to arrays of Google Maps vectors as there aren't really Google Maps equivalents of MultiPoint, MultiLineString, etc.
