The impressive and/or insane thing about the New York City Tree Map is that it maps individual trees: now about 860,000 of them, all managed by the city’s parks department on city streets and in parks, down to the species and trunk diameter, which also means you can filter for those parameters, plus get most recent inspection and tree care data on specific trees. You can even favourite individual trees. If trees had social media accounts, they’d be here. [Bloomberg CityLab]

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.

Fall foliage maps, which show the best times and places to observe autumn leaves, have been a thing for a good long while. The Washington Post’s take on them is something earnestly next level, with a detailed explanation of the biology and satellite images showing the change in colour across the United States. (I don’t need fall foliage maps: I live on an acre of beech and maple forest and get all the fall colours right outside my window, though here in Canada the leaves are almost all on the ground by now.)
