Prefer a paper map to you Iphone??? Take a look a the Zoomable Paper Map of London; ‘map2′
map2 is a pocket-size map which allows you to quickly find what you need without wrestling against a king-size map. map2 removes the need to unfold unnecessary parts or the entire map. map2 lets you zoom into greater detail. In a single folding action chosen parts of a smaller scale map can be unfolded to give an enlarged and more detailed view of that same area underneath. When the map is folded to its minimum size either of the sections facing outwards can still be quickly unfolded and refolded, allowing immediate magnification or miniaturisation. Since the map can be folded to keep any two of the sections on the outside, you can decide which section is visible for quick consultation.
