“…Throughout the empirical literature, digital mapping methods have been used extensively in the physical sciences, particularly for gauging current human-environmental phenomena and for future projections. Such examples include the investigation of global environmental issues (Idrizi, Meha, Nikolli, & Kabashi, 2012), calculations on the global costs of fishing (Lam, Sumalia, Dyck, Pauly, & Watson, 2011; Stewart et al, 2010) and other food security issues (Matsumura et al, 2009), the preservation of global forests (Potapov et al, 2008; Wulder, White, Magnussen, & McDonald, 2007), as well as the effects of climate change and water availability (McDonald et al, 2011). These and other studies that mapped ecological sustainability via a process of global mapping (Sutton, Anderson, Tuttle, & Morse, 2012) are of great interest to our work as they each, in their own distinctive way, set out to develop new methods for measuring anthropogenic environmental impact.…”
