Abstract :
It is important to estimate paddy field areas accurately in order to evaluate the production of rice and the the emission flux of the greenhouse gas “methane”. Accordingly, the authors developed a method to estimate the area of paddy fields in pixels from the CCT count of the Landsat TM data. The authors applied their method to 8 cities and towns located in Ishikari plain of Hokkaido and could estimate those paddy field areas within 2% error
