抄録: A Watergate in the Isahaya bay was closed because of reclamation construction which started in 1989, and water conversion became a very serious problem. Then, remote sensing research was carried out with a few centimeters of resolution and 6 bands. Pictures were taken by UAV and a digital camera on the ground with two infrared filters from May to August in 2016. The research had the following four processes. First process is acquiring photograph data. The data of RGB was acquired by UAV directly, and the ocean temperature data were acquired from Japan Coast Guard. Second, multivariable analysis was performed. Multivariable analysis was applied for water quality in the Isahaya bay and picture data, and regression lines of water quality were obtained by calculating six bands. Third, using these regression water distributions were mapped by PhotoScan (three-dimensional structure software) each water quality. As a result, UAV was available for water quality estimate. Correlations among the water quality were very high. In this research, mapping water quality in the Isahaya bay was successful for environmental management using UAV. The advantage of mapping was visualization of numerical analysis for water quality.
