Such images have a single band that “combines” the information from the visible bands of blue, green and red. In other words, the band is formed by using the total light energy in the visible spectrum (instead of partitioning it into different spectra). It renders a single intensity value per pixel that is commonly visualized in a greyscale image. Information contained in each pixel of a panchromatic image is, therefore, directly related to the total intensity of solar radiation that is reflected by the objects in the pixel and is detected by the satellite sensor.
