The Corner spawned a 2000 HBO miniseries which was in many ways a prelude to The Wire. But among the advantages of going back to the original book -- such as finding incidents, dialogue, and general observations which didn't make it into the adaptation of The Corner, but instead found their way into The Wire's various seasons -- is its inclusion of a detailed map of the West Baltimore "corners" circa 1993.
I've been dabbling with making (via Ortelius) a better version (work in progress above), since the only digital version I could find (see below) was pretty low-res, and couldn't be manipulated in ways that might come in handy later. (Also, making my own version of city maps helps sidestep some annoying copyright troubles with Google maps etc. were the dissertation ever published.) This is a bit of a dry run for a more ambitious map of locations from The Wire, as well as adapting some Batman and Zelda video game maps, since one of the recurring themes of the project will be the spatial aspects of new media epics.
