TEMPORAL SPECTRAL MEASUREMENTS OF RICE CROP WITH THE GSFC MARK-II THREE BAND HAND-HELD RADIOMETER by A.J. CHEN H.T. WANG QC. TIN Department of Atmospheric Physics National Central University Chung-li, Taiwan Republic of China I. INTRODUCTION In the past, we had tried to utilize Landsat MSS data for agricultural resource assessment in Taiwan. Our case study indicated that over-all accuracy was about 88% for estimating the acreage of the paddy field. As the land-use patterns and cultivated practices are very complicated in Taiwan, the spectral and spatial resolutions of the Landsat MSS data substentially limit its applications to various resource inventories. Recently, Taiwan Forestry Bureau scanner system, which consists of Daedalus DS-1260 Digital Scanner (12 channels), DS-1860 Digital Multispectral Preprocessor, DS-1840 B/W Film Converter and DS-1813 Color-Film Printer. The whole system is now in full operation. From the previous experiences, it becomes apparent that utilization of MSS data alone is not sufficient enough for practical applications. Ground-based in situ remote sensing studies are needed to better understand the physics between the natural materials and their reflectances as a function of wavelength. During normal operation, the airborne scanner scans a wild angle of + 40° across the flight path, and receives the reflected sunlight under a range of sun angles. It is thus important to determine the angular reflectance features of natural targets characterized by the bidirectional reflectance distribution function BRDF. If the BRDF exhibits significant anisotropy, the correction procedures must be followed to properly utilize the multispectral and multitemporal data sets taken under different illumination angles. In this report, we employ one GSFC Mark-II Three Band Hand-Held Radiometer, developed by NASA/Goddard Space Flight Center, for taking the bidirectional reflectance of rice crop over its various growing stages. The consensus is to find out the features of the bidirectional reflectance for future utilization of air-borne MSS data.
