These maps are from “legible London”, which is currently used wayfinding signage system in London. It shows the detailed map of each and every parts of the city. The wayfinding system includes different monoliths, accordingly to the area. These monoliths include information about the place, nearby areas, directions and local landmarks etc.
It has two maps on it. One is large city level map and the other one is small area map which shows local attraction of that area and nearby location. It also shows the circle which indicates the distance you can cover in 5 minutes by walking. What really interesting about this map is it shows building facades and building elevation. So it no longer a 2D map instead, it also helps being outsider to find the way much easier by relating the building facades on their way.
Also colour combinations used in these map are easier to read (navy blue-yellow for background and white-black are for fonts).
It has all the information about the particular area with legend on it.
