Webb•T “eh internal average reflectance” (IAR) approach (Kruse) calculates the average spectrum of a scene. The spectrum of any pixel in the scene is then divided by the average spectrum to estimate the relative reflectance spectrum for the pixel. •T “eh flat field” approach assumes there is an area in the scene that has WebbSelect the optical data file and the Radiometric Calibration dialog opens.

Webb16 maj 2013 · IAR reflectance correction has been used with considerable success in arid regions (Kruse 1988; Ben-Dor et al. 1994 ). IAR reflectance is calculated by determining an average spectrum for an entire imaging spectrometer data set and dividing each spectrum in the data set by the average spectrum. s and p 400 index fundWebbThe IAR Reflectance Correction dialog appears.
