9. landsat 5 - compute the toa reflectance for a land pixel in band 4 given that the data was collected at 10: 30 am on june 2nd 2004. the at-sensor dn = 150. use the tables below (reference gyanesh chander and brian markham revised landsat-5 tm radiometric calibration procedures and postcalibration dynamic ranges. ieee transactions on geoscience and remote sensing, vol. 41, no. 11, november 2003.) and the calibration equation to compute radiance on top of atmosphere (toa), and look up the in-band and spectral irradiance value to compute the toa reflectance. show your work. hint: lλ= gain*dn + intercept gain=grescale and intercept=brescale
