Blue Crow Media, which for the past few years has published a series of maps focusing on urban architecture, sent me samples of two of their most recent maps. The Great Trees of London Map is the first of a series of maps highlighting noteworthy trees in a city’s urban forest (Amazon). (A similar map for New York is forthcoming.) The second is another in their line of architecture and urban design maps: Pyongyang Architecture Map features 50 buildings in the reclusive North Korean capital, and includes text and photographs shot by Guardian architecture critic Oliver Wainwright (Amazon). An architecture map of Tbilisi, Georgia, in English and Georgian, has also been released (Amazon). Each map costs £8.
