Estimation of the rice-planted acreage is divided into two processes, discrimination of the rice-planted area and totalization of the riceplanted area. Satellite radar remote sensing is effective for discriminating the rice-planted area, because the growing season for rice in Japan, overlaps with the rainy season. Furthermore, the rice-planted area can be accurately totalized by referring to agricultural plots vector data. In order to improve the estimation accuracy of the rice-planted acreage, a method which discriminates the rice-planted area using satellite radar data and totalized the rice-planted area referring to agricultural plots vector data was proposed in this paper. The proposed method was applied to RADARSAT data to estimate the riceplanted acreage for a test site in Koshiji, Niigata prefecture. The estimated rice-planted acreage obtained by the above method was compared with that acquired by QuickBird data. As a result of accuracy verification, the accuracy of estimation using the above method was 85%.
