Mark Ovenden has made a career of publishing books about transportation systems and their maps that are both comprehensive and copiously illustrated. These include books about transit maps, railway maps and airline maps, as well as books about specific transit systems like the London Underground and the Paris Metro.
His latest, Underground Cities (Frances Lincoln, 22 Sep), is in some ways a natural progression from his past work: in the introduction he muses on the link between transit geekery and wondering about “what else lies down there beyond the walls” (p. 6). But in other ways this is quite a different book.
Speaking of Washington, the D.C. Underground Atlas is a project to map all the tunnels under the city: utility, transportation and pedestrian tunnels alike, from metro and water tunnels to the underground corridors connecting congressional buildings. The maps are presented as Esri Story Maps and there’s lots of accompanying text. The project is the brainchild of Elliot Carter, who is profiled by CityLab and the Washington Post: both pieces reveal one challenge in mapping the underground infrastructure of Washington—getting past security concerns.
