Use of New coastal spectral band for precise dwelling extraction in the Hagadera refugee camp

An increasing number of recent and upcoming satellite platforms are equipped with on-board multispectral sensors that are capable of recording reflected sunlight at the transition from visible blue to violet wavelength. Those sensor capabilities were originally developed for coastal and shallow water applications. This paper presents a new application area of such sensor bands for image information extraction. According to our observations the so called coastal band of Worldview 2 imagery reflects strongly on bright coloured plastic. Such material is widely used in form of plastic sheets provided by relief agencies to roof temporary dwellings in refugee or internally displaced person (IDP) camps. The excellent reflection within this band allows a precise automated detection of dwellings for such camps. The presented method uses this band as input image for a morphological processing to extract single dwelling.
