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.

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

  •    Javascript

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

  •    C++

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.

  •    C++

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

  •    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.

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).


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.

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.

Tile38 - Geospatial database, spatial index, and realtime geofence

  •    Go

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.

django-rest-framework-gis - Geographic add-ons for Django REST Framework

  •    Python

Geographic add-ons for Django Rest Framework - Mailing List. Provides a GeometryField, which is a subclass of Django Rest Framework (from now on DRF) WritableField. This field handles GeoDjango geometry fields, providing custom to_native and from_native methods for GeoJSON input/output.

us-atlas - Pre-built TopoJSON from the U.S. Census Bureau.

  •    Shell

This repository provides a convenient mechanism for generating TopoJSON files from the Census Bureau’s cartographic boundary shapefiles, 2015 edition. A TopoJSON topology containing three geometry collections: counties, states, and nation. The geometry is quantized, projected using d3.geoAlbersUsa to fit a 960×600 viewport, and simplified. This topology is derived from the Census Bureau’s cartographic county boundaries, 2015 edition. The state boundaries are computed by merging counties, and the nation boundary is computed by merging states, ensuring a consistent topology.

world-atlas - Pre-built TopoJSON from Natural Earth.

  •    Shell

This repository provides a convenient mechanism for generating TopoJSON files from Natural Earth’s vector data, version 2.0.0. A TopoJSON topology containing two geometry collections: countries and land. The geometry is quantized, but not projected; it is in spherical coordinates, decimal degrees. This topology is derived from the Natural Earth’s Admin 0 country boundaries, 1:110m small scale, version 2.0.0. The land boundary is computed by merging countries, ensuring a consistent topology.

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.

  •    Javascript

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.
