This repository contains GeoJSON data for all the countries boundaries including boundaries for states of bigger countries (note that this repository is currently filling). Detalization is good for using this data on scales up to 1:10000000 / gmaps zoom 6-7 (it's the best quality in combination with free-to-use license). Data is created using geojson.io tool.

You can either download it or install in your project either via Composer or NPM:

Via Composer:

"require": {
  "georgique/world-geojson": "^3.0"
}

Via NPM:

"dependencies": {
  "world-geojson": "^3.0",
}

Help with integrating it with any other Package Manager is welcome.

JSON files can be read from the directory in which the package was downloaded.

Node.js applications can use the provided helper functions to synchronously load the JSON as a JavaScript object.

const geoJson = require('world-geojson') // or `import * as geoJson from 'world-geojson'`

geoJson.forCountry('Antigua & Barbuda'); // returns the contents of /countries/antigua_and_barbuda.json
geoJson.forState('Australia', 'New South Wales'); // returns the contents of /states/australia/new_south_wales.json
geoJson.forArea('U.S.A.', 'U.S. Virgin Islands'); // returns the contents of /areas/usa/us_virgin_islands.json

// Combine multiple GeoJSONs into one
const combined = geoJson.combineGeoJson([
  {countryName: 'Antigua & Barbuda'},
  {countryName: 'Australia', stateName: 'New South Wales'}, 
  {countryName: 'U.S.A.', areaName: 'U.S. Virgin Islands'} 
]);

This release is about gluing borders between all the countries so they perfectly align. Was / Is:

Also, NPM this package can now be installed via NPM

• Glued borders for AU states (100% - published in 3.1)
• Better Canadian province borders (0%)
• Glued borders for Canadian provinces (0%)
• Better USA state borders
• Glued borders for USA states (0%)

Countries which we are going to provide state boundaries for:

• Australia (ready)
• Argentina (pending: 24)
• Brazil (pending: 26)
• Canada (ready / OSM / low quality)
• China (pending: 33)
• India (pending: 29)
• Indonesia (pending: 34)
• Kazakhstan (pending: 14)
• Mexico (pending: 31)
• Philippines (pending: 18)
• Russia (pending: 83)
• USA (ready, OSM data)

Note that some states boundaries are provided by OSM, however quality of that data is much lower. It's planned to replace them with handmade ones eventually.

• Providing geojson for any regions - not necessarily from the roadmap above, any country's regions can be included
• Integration with any package managers other than NPM and Packagist

• GitHub Repository
• Composer package
• NPM package
• Tool for editing GeoJSON - geojson.io
• OpenStreetMap

This library is my personal mini-project which I enjoy doing and I am happy if that is useful for anyone else. If you want to thank me, feel free to buy me a cup of coffee through the GitHub Sponsor program.
