  You have to navigate graphically - can't input UK roads. You can make maps, upload photos and video and share the maps (private or public) with others via email or convenient URL linking. Each of the public maps allow for comments, contributed text, media and ratings. Also, since each of the photos on the map belong to an album, you can also browse through these albums. Ugly interface
