Japan Agriculture executes growth survey and soil survey every year as part of farming guidance for quality improvement and maintenance of rice. The technology that expands the ground data such as growth survey data and soil survey data is requested however a lot of time and labor are necessary for growth survey and soil survey. Then, use of excellent satellite data in wide-ranging information acquisition is examined. This study is purpose of development of large area grasp technique to condition of paddy soil and condition of growth of rice. This study result shows possible in ggrasp of paddy riceh, grasp of paddy field where humus is low by using the optical sensor data at time covered of water and in ggrasp of growth of riceh, grasp of leaf year that is important growth parameter using the radar data.
