Once with the development of remote sensing techniques, hyperspectral images become a valuable tool, with a wide range of uses usually for detection of the size and shape of urban areas. A hyperspectral image is a three-dimensional image that contains valuable spectral information, where each pixel is represented by more than one hundred spectral bands that cover the visible to short infrared wavelength range. More exactly, a hyperspectral image is typically a three-way block of data also called hypercube or tensor.
