The study area is located in the suburbs of Mullewa, Western Australia. Various data used included spectral reflectance of wheat measured from the ground and those measured using airborne sensors, wheat growth conditions data, such as LAI, SPAD values, and wheat height, and sample analysis data, including biomass, grain nitrogen content rate, leaf nitrogen content rate, and ash content, of the later grain filling and heading stages. This study consisted of (1) selection of estimation items regarding the wheat yield, quality, and growth conditions by correlation analysis of sample data, (2) definition of estimate equations for selected items, (3) verification of estimation accuracy, and (4) development of estimation maps. As a result, head moisture, which is related to the wheat growth conditions, was well estimated using hyperspectral data of the later grain filling stage. At the same time, grain weight, which is related to the wheat yield, and grain nitrogen content rate and ash content, which are related to the wheat quality, were well estimated using hyperspectral data of the heading stage. This study implies that it is possible to visualize the wheat yield, quality, and growth conditions on a regional scale using hyperspectral data. 1. INTRODUCTION 2. STUDY AREA Australia plays a key role to ensure food security of Japan. The study area is located in the suburbs of Mullewa, Western Approximately 9096 of wheat consumed in Japan is imported Australia (Figure 1). The area is approximately 480km? with from overseas countries. Among all countries, Australia is the mostly flat land features, and is mainly used for wheat, canola, thrid most important country because raw materials used to and lupin fields which size is several square kilometers. produce noodles in Japan are imported mostly from Australia. However, the Australian wheat production is vulnerable to natural disasters such as droughts. Therefore, it is desirable to develop the growth monitoring system to ensure the stable Australian wheat supply in the future. Profitable agriculture requires efficient and precise estimation method for crop growth monitoring. Spaceborne sensors with a high wavelength resolution can improve the efficiency and precision of the estimation. The Ministry of Economy, Trade and Industry (METI) of Japan plays a leading role in the development of the satellite-borne hyperspectral sensor, HISUI (Hyper-spectral Imager SUIte), and researches on fundamental technology for hyperspectral data's applications in various fields such as energy, natural resources, agriculture, forestry, and the environment. In the field of agriculture, hyperspectral imaging is experimentally used to estimate the yield, quality, and growth of rice and wheat. Accordingly, we evaluated methods to estimate the wheat yield, quality, and growth conditions using ground-based and airborne hyperspectral data of the later grain filling and heading stages in Western Australia. Figure 1: Study Area 3. DATA USED The first field survey was conducted in the late October, which is around the same time as the later grain filling stage of wheat, of the year 2009 (Table 1).
