Geographical boundaries of states/provinces -> Google Maps Polygon

Question

I\'m building a web application that is going to dynamically highlight certain U.S. states and Canadian provinces on a Google Map, based on buttons and click events.

Answer 1

I've got XML for US state polygons here. I use them like this.

I deliberately kept the detail fairly light to reduce the loading time and end up with a map that's reasonably responsive in slow browsers.

I don't have anything for Canada.
