Part of the Springer Remote Sensing/Photogrammetry book series (SPRINGERREMO)


The origin of the digital numbers in orbital images is presented from both users’ and engineer’s point of views. This chapter aims to clarify important details of the generation of the digital numbers, which keep the spectral mixture, the central theme of this book.
