Annotated Atlas TopoJSON
This is a fork of topojson/world-atlas that merges in topojson/us-atlas and other shapefiles.
It leaves all the original shapefile metadata attached, meaning the resulting files are not optimised for web-use but are much easier to use, particularly in non-production settings.
Usage
In a browser (using d3-geo and Canvas), bl.ocks.org/3783604:
<!DOCTYPE html>
<canvas width="960" height="500"></canvas>
<script src="https://d3js.org/d3.v4.min.js"></script>
<script src="https://unpkg.com/topojson-client@3"></script>
<script>
var context = d3.select("canvas").node().getContext("2d"),
path = d3.geoPath(d3.geoOrthographic(), context);
d3.json("https://unpkg.com/world-atlas@1/world/110m.json", function(error, world) {
if (error) throw error;
context.beginPath();
path(topojson.mesh(world));
context.stroke();
});
</script>In Node (using d3-geo and node-canvas), bl.ocks.org/885fffe88d72b2a25c090e0bbbef382f:
var fs = require("fs"),
d3 = require("d3-geo"),
topojson = require("topojson-client"),
Canvas = require("canvas"),
world = require("./node_modules/world-atlas/world/110m.json");
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"));File Reference
# world/110m.json <>
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.
# world.objects.countries
# world.objects.land
# world/50m.json <>
Equivalent to world/110m.json, but at 1:50m medium scale.
