OpenStreetMap is a free editable map of the whole world. It is made by people like you. OpenStreetMap allows you to view, edit and use geographical data in a collaborative way from anywhere on Earth.

You can export data as XML or as SVG, Postscript etc. The site has a description of the XML format.

Also note that Google maps has an API which can be used to display your own paths projected onto a Google map.
