On Wednesday evening, OpenStreetMap will be mapping the area south of the Thames to the west of London Bridge and North of South Bermondsey.
The easiest way to think of OpenStreetMap, is the Wikipedia, but for maps.
OpenStreetMap maps are better than commercial providers for a variety of reasons including:
* the data includes useful things like footways, cycleways, points of interest, and building outlines, that commercial mapping providers don't care about
* the best single source of pubs in terms of name and location (though there are plenty more to add)
* the underlying vector data is available for everyone to use, as long as you say where you got the data from
* you can do significantly more with the data, such as put them into your own mobile application
* you can update the data, without having to wait for some commercial company to eventually update it (and possibly include deliberate errors)
