Research Abstract	In this work, I examined the potential of shoreline change analysis and developed the shoreline tracing method by using JERS-1/SAR and ALOS/PALSAR amplitude images. I also approached focusing on Kujyuukurihama beach in Chiba Prefecture, Enshunada Beach in Shizuoka prefecture, Tottori Sand Dunes in Tottori prefecture, Fukiagehama Beach in Kagoshima prefecture, Tokachi beach in Hokkaido prefecture, Mukawa beach in Hokkaido prefecture, Itoigawa beach in Niigata prefecture, Hyuuganada beach in Miyazaki prefecture and Kaminokawa beach in Kagoshima prefecture as my test site. My proposed shoreline tracing method reproduced the temporal variation of the Kujyuukurihama beach using JERS-1/SAR and ALOS/PALSAR amplitude images. Moreover, I could analysis the surface deformation by SAR Interferometry techniques using ALOS/PALSAR dataset. As a result, I could offer simultaneous display method between shoreline tracing results and surface deformation results as spatial information, repectively.
