In addition to monitoring of the urban heat island effect, other typical applications related to urban environment with HRS have been also carried out over the past decades. These included the identification of roof sheet iron manufactured by different corporations surrounding the Beijing Asian Games village[122]. As shown in Fig.20, it is hard to tell apart the blue iron sheets separately from Dalian of China, South Korea and another Chinese corporation with the visible wavelengths. However, they are clearly distinguished from each other due to taking full advantages of hyperspectral remote sensing information by the convex geometry projection method.
