Nowadays our orientation is very often not longer based exclusively on the actual geography and their landmarks. There are loads of alternatives, from street numbers to GPS routing in our smartphones, to guide us to a destination. All of those wayfinding devices have in common that they are abstracted projections of the real world’s spatial arrangement. Which brings us to two interesting implications: First, because abstraction means in this case a decrease of information, something is lost. And second, the longer you are using a device the more you accept it or get used to it. For instance the geographical structure of transportation networks are often reshaped to provide users with more understandable transit maps. These distortions have a major influence on people’s perception of a city’s geography, to the point they get stored mentally and become the collective representation of the real world’s geography.

‘Metrography’ attempts to explore this phenomenon using the most famous of transit maps: the London Tube Map.
