“…In recent decades, the use of satellite imagery has been increasingly investigated to estimate urban population and density (Wang, Fan, & Wang, 2020;Lu, Jungho, Quackenbush, & Halligan, 2010;Hillson et al, 2019;Ogrosky, 1975;Dittakan, Coenen, Christley, & Wardeh, 2013), mapping land cover and land-use in urban areas (Carleer & Wolff, 2006;Gamba et al, 2007;Movia, Beinat, & Crosilla, 2016;Novack et al, 2003;Ouyang et al, 2011;Voorde, Van, William, & Canters, 2007), and also for tracking changes in the urban landscape (Volpi, Tuia, Bovolo, Kanevski, & Bruzzone, 2013;Zhang, Peng, & Huang, 2018;Lv, Liu, & Benediktsson, 2020). Remote sensing has also been used to detect informal settlements in urban areas, which is the first step to upgrade the most vulnerable communities (Fallatah, Jones, & Mitchell, 2020;Weir, McQuillan, & Francis, 2019).…”
