Mapping Central Park’s 19,630 Trees
This preposterously detailed map of New York’s Central Park took two years to survey and includes every trail, building, monument, recreational area and waterway in the park. It also includes every single tree — all 19,630 of them. (See the story behind the map and videos about the map.) The map is available as a 59×17-inch poster for $35. Via Kottke.
