How can I get so much position data when drawing a map like the Australia Map demo?

[faithwangyang]

Now in China we want to make a China Map demo

just like the Australia Map demo(raphaeljs.com/australia.html).

I guess by so much position data can we draw out the province’s shape.

My question is,

　 How can I get so much position data?

Obviously getting these position data manually is a very difficult task.

Is there any method or tool which can give us help when needing the map’s shape position data?

Try getting a china map in svg and converting it to raphael element, use https://github.com/tomasAlabes/rappar
