cartagen - Client side framework for creating vector maps in HTML5

Cartagen from Jeffrey Warren is a client framework to build vector-based maps in HTML5.

Here’s a quick video demo:

One interesting feature is how Cartagen uses GSS, or a CSS vocabulary for geospatial data:

waterway: {
  fillStyle: "#57d",
  strokeStyle: "#24a",
  lineWidth: 4,
  pattern: "/images/pattern-water.gif"
},
water: {
  strokeStyle: "#24a",
  lineWidth: 4,
  pattern: "/images/pattern-water.gif"
},
highway: {
  strokeStyle: "white",
  lineWidth: 6,
  outlineWidth: 3,
  outlineColor: "white",
  fontColor: "#333",
  fontBackground: "white",
  fontScale: "fixed",
  text: function() { return this.tags.get('name') }
}

Cartagen comes in both client and server editions
