What are multidata and multiband images? White their advantage
Answers
Remote Sensing sensors record earth's reflectance in different wavelength and these received reflectance value are processed to create separate image for each wavelength. The reflectance value stored for different wavelength in different layers, which are also called bands present in that satellite images.
Multi band images also known as multi spectral satellite images. Multi band image simply define, when more than one band/spectrum and at least three wavelength data recorded by sensor to create composite of satellite images. A sensor can record several wavelength simultaneously and it is completely depend upon sensor characteristics and capabilities.
As it is already studied that sensor can record earth surface feature in different wavelength from visible spectrum to infrared spectrum. The reflectance recorded from different
