# World Atlas TopoJSON

This repository provides a convenient redistribution of [Natural Earth](http://www.naturalearthdata.com/)’s [vector data](http://www.naturalearthdata.com/downloads/), version 4.1.0 as TopoJSON. For earlier editions, see [past releases](https://github.com/topojson/world-atlas).

A [TopoJSON file](https://github.com/topojson/topojson-specification/blob/master/README.md#21-topology-objects) containing the geometry collections <i>countries</i> and <i>land</i>. 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](http://www.naturalearthdata.com/downloads/110m-cultural-vectors/), 1:110m small scale. The land boundary is computed by [merging](https://github.com/topojson/topojson-client/blob/master/README.md#merge) countries, ensuring a consistent topology.

Each country has two fields:

* *country*.id - the three-digit [ISO 3166-1 numeric country code](https://en.wikipedia.org/wiki/ISO_3166-1_numeric), such as `"528"`
* *country*.properties.name - the country name, such as `"Netherlands"`
