"OpenStreetMap is a wiki-style map of the world that anyone can edit. You can get the raw data for roads around the world, set up a server, design a new map style, and have your own personal online interactive maps. In the past, this has been difficult owing to the large volume of data required and the hassles of system administration. Tile Drawer is designed to make this process easy with a custom-configured Amazon EC2 machine image (AMI) that gets you up and running with just two pieces of information: a custom stylesheet that you choose, and the geographical location of a part of the world you'd like rendered."
