英文摘要
Many aquatic macrophytes have been endangered. Therefore, it is necessary to develop the monitoring techniques urgently. In this study, a classification technique using sidescan sonar images (backscattering strength) was developed for mapping of the macrophyte distribution. As a result of various classifications, it was found that accurate classification was provided by difference of backscatter strength between seasons which was indicating the macrophytes phenology. It was considered that the accurate monitoring of aquatic macrophyte in a wide area was enabled by the classification technique.
