| Outline of Final Research Achievements |
In this research project, the optimum specifications of remote sensing observation of wetland environment were chased for aiming the wetland ecosystem conservation. The high moor area of Kushiro wetland was selected as the study site and a very fine map of plant community was created by using high spatial resolution color aerial photos. By examining this fine map of plant community, about 1cm spatial resolution is helpful for visual interpretation of precise plant communities and the spatial resolution from 10cm to 30cm is required for accurately mapping of wetland plant communities.
As for the best timing of observation is from the last ten days of June to the middle ten days of July while groups of sedge are in flower, since flowers of sedge are helpful to tell species of sedge. However, the optimum spectral bands were not clarified due to the low quality of hyper-spectral image to be studied. The optimum spectral bands to observe wetland should be studied in further works.
