This script that generates TopoJSON maps with one command line.

Prerequisites

  • -r | --resolution=<string> : Map resolution (10m, 50m, 110m) [default: 110m]
  • -a | --skip-antarctica : Remove Antarctica from the map [default: false]
  • -s | --include-states : Include States/Provinces lakes on the map [default: false]
  • -l | --include-lakes : Include Great lakes on the map [default: false]
  • -p | --include-projection : Embed projection into the topojson file

  • CONTINENT
  • ISO_A2

Projection

At the moment the only projection used on this script, when you add the parameter -p, is an equirectangular and a size 960x500:

width = 960, height = 500, d3.geo.equirectangular().rotate([-11.0, 0.0, 0.0]).scale(width /(2 * Math.PI)).translate([width / 2, height / 2])

You can edit it on the script if you targeting another projection. Here's [an example](Here's an example of where it's used) of where it has been used
