which-country-ne-10m

Get ISO 3166-1 alpha-3 country code for geographic coordinates in node.js or browser.

Forked from the original which-country library, this uses Natural Earth's 10m countries database instead of the 50m one which should provide higher accuracy and support for smaller territories but at the cost of performance and size.

Powered by rbush and modified Natural Earth 10m countries dataset.

If you are interested in more general solution, try which-polygon.

Usage

npm install which-country-ne-10m

and then:

var wc = require('which-country-ne-10m');

// pass [lng, lat]
console.log(wc([37, 55])); // RUS
console.log(wc([-100, 40])); // USA
console.log(wc([40, -40])); // null, somewhere in Atlantic Ocean
