Abstract

In December 1995 an inflight calibration campaign was conducted in India for the LISS-2 cameras onboard the IRS-1B satellite. For this purpose three test sites were selected where ground reflectance measurements were performed simultaneously with overpasses of the IRS-1B and Landsat-5 satellites. Due to weather conditions, only the data of 8 December 1995 was appropriate for the evaluation of the LISS-2 calibration coefficients. Ground truth data of several reference areas in ICRISAT near Hyderabad was jointly collected by DLR, ISRO, and GFZ using two field spectrometers and a 4-band radiometer. Weather data was recorded at a local meteorological station. The ATCOR2 model, based on the MODTRAN 2 radiative transfer code, was employed to calculate the calibration coefficients for the LISS-2B sensor. The derived inflight calibration coefficients agree within 5 percent with the preflight coefficients. The offset coefficients were not evaluated since no low reflectance target was available at this time.
