Calibration of the Casi Airborne Imaging Spectrometer and Application to Generating Reflectance Imagery

摘要

Successful application of remote sensing to practical problems is best accomplished using measurements of intrinsic characteristics of the scene. One such characteristic is the reflectance, or more correctly the Bi-directional Reflectance Factor (BRF) (O'Neill et al 1995). Unfortunately most sensors do not measure BRF but reflected at-sensor radiance. An appropriate strategy must be used to convert at-sensor radiance values to at ground reflectance.
