This is a new 'geographically accurate' London underground map by Mark Noad. Harry Becks original version was created as a digram, a visually easy to read piece of information, simplified. This one I don't like so much, its not so easy to read. It is helpful if you intend to walk overground from station to station. I am looking at this as someone who knows London though and could make my way round without too much trouble, perhaps a tourist whose never been to London might like it? Luckily this is just an alternative, it is not a replacement to the current map system.
