If the main online mapping apps don't deliver the results you need, then ScribbleMaps may be able to help. This handy web service takes a base Google Maps view of your location, then allows you to customise it with lines, shapes, captions, icons and descriptions.

A URL allows you to share the results directly with anyone who might be interested, or you can use an embed code to add the map to your website or blog. Either way, any visitors can then post comments, and if you've produced something really special then they're even able to share the map on Facebook, Twitter, Digg and other social media sites.
