OpenStreetMap can be extremely detailed – take Boston for example. This shows the shape of things to come and the power of OpenStreetMap. Every T-stop (subway), building and park are mapped in Boston. The walking paths through the all the parks are mapped, even the airport terminals are marked and so are the hospitals and libraries.  OpenStreetMap provides the opportunity to map more on one map than has ever been mapped before.  Add content, edit content and help create the most comprehensive maps.
