sensing techniques to detect land use change in coal mining areas (Du et al. 2007; Gao et al. 2009). In most of these studies, land use was mapped by extracting information from remotely sensed datasets using traditional pixelbased classifiion techniques (Prakash and Gupta 1998; Townsend et al. 2009; Bian and Lu 2013). These techniques only use spectral information in the image classifi ...
