“…Third, environmental scientists are increasingly relying upon remote sensing to derive urban land cover information as a primary boundary condition used in many spatially distributed models (e.g., Lo, Quattrochi and Luvall, 1997;Lo and Quattrochi, 2003;Arthur-Hartranft, Carlson and Clarke, 2003;Carlson, 2004;Stefanov and Netzband, 2005;Hepinstall, Alberti and Marzluff, 2008). Lastly, the global change community has recognized remote sensing as an enabling and acceptable technology to study the spatiotemporal dynamics and consequences of urbanization as a major form of global changes (e.g., Bartlett, Mageean and O'Connor, 2000;Small and Nicholls, 2003;Auch, Taylor and Acededo, 2004;Small, 2005;Turner, Lambin and Reenberg, 2007;Grimm et al, 2008), given the facts that more than half of the global population are now residing in cities (UN-HABITAT, 2010) and urban areas are the home of major global production and manufacture centers (Kaplan, Wheeler and Holloway, 2009).…”
