Just trying to get some idea of how New York works. This is a very random mish-mash of notes and links, from which i will attempt to assemble a psychogeographical gestalt. The idea is to first establish a general geographical orientation, then to take simultaneous bottom-up (reading about individual places) and top-down (looking at the history of the growth of the city, looking at the overall structure of the trunk roads and railways) approaches to put flesh on the geographical skeleton.
I need an outline map of the whole city, a specification of how the Manhattan grid system works, that sort of thing.
The Google Maps vs NYC Subway thing is pretty neat.
