Description

We presumed the rice grain protein content rate using image of IKONOS, sensors in Budokubo and Hanzogane region which were the stricken area of a Cyuuetsu great earthquake.. As a result, significant relation was admitted between the rice grain protein content rate and the band 2 of IKONOS data in Budokubo region. In Hanzogane region, relation was admitted between the rice grain protein content rate and normalized difference vegetation index (NDVI) 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 derstood from the map in the sight and the large area. To obtain the regression of higher accuracy,it is necessary to examine the ethod 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.
