Paper Abstract

Resourcesat-1(IRS-P6) was built by Indian Space Research Organisation and launched in October, 2003. Resourcesat-1 carries three imaging sensors--a moderate resolution camera Advanced Wide Field Sensor (AWFS), a moderate resolution Linear Imaging Self Scanning-III device (LISS-III) and a high resolution Linear Imaging Self Scanning-IV device (LISS-IV) to get different spatial resolution image. Apparent reflectance of LISS-III image is calculated in Poyang Lake, south of China. The mean Digital Number (DN) in Red Band image of part of this district is 108.9, and Stdev is 62.72. The mean apparent reflectance of this image is 0.17, and Stdev is 0.093. Apparent reflectance can be used in the normalized difference vegetation index (NDVI) calculation, atmospheric correction, and others. NDVI value which is calculated by apparent reflectance can represent surface status accurately.
