Google has had tools for creating custom maps for a while, but they haven't been very accessible -- especially not if you've wanted to find your friends' creations. It should be easier to track down those hand-made tourist guides and trail markers after today, though. Google has relaunched Maps Engine Lite as the much catchier My Maps, and has expanded the Google Maps Gallery to include everyone's projects, no matter what their focus. So long as you want to make your cartography public in the first place, anyone can find it sitting alongside the Gallery's usual historic and government info. Google will transition every Maps Engine Lite user to My Maps by the end of the year, but you can upgrade early if you just can't wait to share your favorite bike path with the rest of the world.
