		# World Atlas TopoJSON

		This repository provides a convenient mechanism for generating TopoJSON files from [Natural Earth](http://naturalearthdata.com/).
		This repository provides a convenient mechanism for generating TopoJSON files from [Natural Earth](http://www.naturalearthdata.com/)’s [vector data](http://www.naturalearthdata.com/downloads/), version 2.0.0.

		## Installing via Homebrew
		### Usage

		Before you can run `make`, you’ll need to install Node.js. Here’s how to do that using [Homebrew](http://mxcl.github.com/homebrew/) on Mac OS X:
		In a browser (using [d3-geo](https://github.com/d3/d3-geo) and Canvas), [bl.ocks.org/3783604](https://bl.ocks.org/mbostock/3783604):

		```bash
		brew install node
		```
		```html
		<!DOCTYPE html>
		<canvas width="960" height="500"></canvas>
		<script src="https://d3js.org/d3.v4.min.js"></script>
		<script src="https://d3js.org/topojson.v2.min.js"></script>
		<script>

		And then, from this repository’s root directory, install the dependencies:
		var context = d3.select("canvas").node().getContext("2d"),
		path = d3.geoPath(d3.geoOrthographic(), context);

		```bash
		npm install
		d3.json("https://d3js.org/world-110m.v1.json", function(error, world) {
		if (error) throw error;

		context.beginPath();
		path(topojson.mesh(world));
		context.stroke();
		});

		</script>
		```

		If you want to install this software using an alternate method see the website for [TopoJSON](https://github.com/mbostock/topojson). I also recommend reading my tutorial, [Let’s Make a Map](http://bost.ocks.org/mike/map/).
		In Node (using [d3-geo](https://github.com/d3/d3-geo) and [node-canvas](https://github.com/Automattic/node-canvas)), [bl.ocks.org/885fffe88d72b2a25c090e0bbbef382f](https://bl.ocks.org/mbostock/885fffe88d72b2a25c090e0bbbef382f):

		## Generating TopoJSON
		```js
		var fs = require("fs"),
		d3 = require("d3-geo"),
		topojson = require("topojson-client"),
		Canvas = require("canvas"),
		world = require("./node_modules/world-atlas/world/110m.json");

		Once you have everything installed, simply run:
		var canvas = new Canvas(960, 500),
		context = canvas.getContext("2d"),
		path = d3.geoPath(d3.geoOrthographic(), context);

		context.beginPath();
		path(topojson.mesh(world));
		context.stroke();

		canvas.pngStream().pipe(fs.createWriteStream("preview.png"));
		```
		make
		```

		This will generate various TopoJSON files in the `topo` directory. As a by-product of producing these files, you’ll also download the shapefiles directly from Natural Earth and convert them into GeoJSON and filter.
		## File Reference

		If you want to generate a custom map, I recommend modifying the Makefile. Or, just use the Makefile as a set of examples, and run the appropriate `ogr2ogr` and `topojson` commands from the terminal.

		A [TopoJSON topology](https://github.com/topojson/topojson-specification/blob/master/README.md#21-topology-objects) containing two 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, version 2.0.0. The land boundary is computed by [merging](https://github.com/topojson/topojson-client/blob/master/README.md#merge) countries, ensuring a consistent topology.
