Great article, The New The New Cartographers, by Jessica Clark, from In These Times:
Maps are everywhere these days. The ubiquity of global positioning systems (GPS) and mobile directional devices, interactive mapping tools and social networks is feeding a mapping boom. Amateur geographers are assigning coordinates to everything they can get their hands onâ€”and many things they canâ€™t. â€œLocative artistsâ€ are attaching virtual installations to specific locales, generating imaginary landscapes brought vividly to life in William Gibsonâ€™s latest novel, Spook Country. Indeed, proponents of â€œaugmented realityâ€ suggest that soon our current reality will be one of many â€œlayersâ€ of information available to us as we stroll down the street.
