説明

We presumed the rice grain protein content rate using image of IKONOS and GeoEye-1, sensors in Budokubo and Yamakoshi ward which were the stricken area of a Cyuuetsu great earthquake. In both regions, relations were admitted between the rice grain protein content rate and normalized difference vegetation index (NDVI) in 2009 data. In addition, we presumed the rice grain protein content rate and made it to the map using obtained regression. The protein content rate was able to be understood from the map in the sight and the large area. To obtain the regression of higher accuracy　,it is necessary to examine the method of acquiring the taking an image satellite date and extraction method of digital number. And, it is necessary to use high resolution satellite data for the protein content rate can be presumed in the case of small rice field.
