RICE YIELD ESTIMATION BY USING OBJECTIVE YIELD SURVEY AND REMOTE SENSING METHODS; CASE STUDY IN SINGBURI AND ANGTHONG PROVINCE

摘要

The research is using remote sensing and objective yield survey to perceive paddy field plantation area and yield production. Moreover this study also find correlation between reflectance derived from spectrometer in field survey and SMMS satellite image in CCD-4 bands. The result of study show reflectance value in 5 stages of rice including sow ing/transplanting, tillering, panicle, flowering and harvesting when in term of satellite image. When knowing reflectance, it is useful for classify paddy field plantation area more quickly and accurately. Besides, this study create two rice forecasting models that one based on yield trend and other based on biomass and harvest index. The result model of rice in study area are fit with model that based on biomass and harvest index.
