TinyMap – Easily Create and Share Maps To Anywhere
http://www.tinymap.net/

tinymap.net allows you to create a map and save it for viewing by yourself or others later on. You can trace out a path with way-points or mark out a point of interest with a graphic icon, and add notes for any of the points. Once you are done, you save the map just as you would like to see it when you return. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
