I found this fairly cool map the other day when surfing over at The Serif.
I’d challenge someone to have a go at doing this for somewhere else. Topological maps like these are some of the more difficult cartographic documents to produce. They only provide information specific to their purpose. With the unnecessary detail stripped out, no scale or definition of distance or direction, they maybe no more than reference tools. What works on trains and buses as a navigation aid however, doesn’t necessarily make a good driving aid. This maybe because in general people find it hard to translate the position of places on such maps to their real world positions.
