“…Thus, in any investigation of urban expansion, the specific geographical, social, and political context must be considered. However, this phenomenon has typically been studied using spatial grids at the city or metropolitan area scale using satellite images with coarse spatial resolution, such as MODIS, Landsat, and SPOT (Cheng & Masser, 2003;Fang, Gertner, Sun, & Anderson, 2005;Gimblett, Daniel, Cherry, & Meitner, 2001;Ji et al, 2006;Martinuzzi, Gould, & Gonzalez, 2007;Sudhira, Ramachandra, & Jagadish, 2004;Tsutsumida, Saizen, Matsuoka, & Ishii, 2013;Weber, 2003). While these sensors are able to observe urban surfaces frequently, the coarse spatial resolution of these images is not sufficient to explore urban expansion because of the mixed pixel problem.…”
