Urban Earth, with studies in Mumbai, Mexico City, and London:  Their approach: “walking across some of Earth’s biggest urban areas, to explore their spatial realities for the people who live there and challenge dominant media discourses regarding the places in which most of us now live.  The idea is to walk a transect across an urban area, taking a photograph every ten steps.” (84) 

The concept reminds me of Christopher Girot’s essay ‘Vision in Motion’ in the Landscape Urbanism Reader (Waldheim, 2006), on the role of new representational techniques and the ability to document the interstitial, non-destination spaces, echoing Conan, the ‘black holes’ in the urban fabric that   “…have become the dominant feature of peripheries and urbanized countries… need to consider these long non-entities as probably equally significant as the most celebrated vistas…” (Waldheim 2006, p.100)
