We applied the SMA for flood event in Bangkok, Thailand, 2011 and compared the result of SMA and visual interpretation from IKONOS image for accuracy velidation. Additionally, we developed an estimation model for calculating the water occupancy based on satellite SAR observation, comparing backscattering coefficients of the ALOS PALSAR image and the water fraction information derived from SMA method, which is applied to the Landsat-7 ETM+ reflectance image observing the 2011 Tohoku earthquake tsunami. By using our proposed formula and SAR imagery after water-induced disasters, we can perform to estimate flooded areas easily and quantitatively.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "公益社団法人 日本地震工学会", "subitem_publisher_language": "ja"}, {"subitem_publisher": "JAPAN ASSOCIATION FOR EARTHQUAKE ENGINEERING", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.5610/jaee.16.3_157"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "篠原 崇之", "creatorNameLang": "ja"}, {"creatorName": "SHINOHARA Takayuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "松岡 昌志", "creatorNameLang": "ja"}, {"creatorName": "MATSUOKA Masashi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "リュウ ウェン", "creatorNameLang": "ja"}, {"creatorName": "LIU Wen", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "山崎 文雄", "creatorNameLang": "ja"}, {"creatorName": "YAMAZAKI Fumio", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_title": "光学衛星画像を用いた混合スペクトル解析に基づく浸水度の定量推定とSAR画像を組み合わせた東北地方太平洋沖地震津波への適用", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "光学衛星画像を用いた混合スペクトル解析に基づく浸水度の定量推定とSAR画像を組み合わせた東北地方太平洋沖地震津波への適用", "subitem_title_language": "ja"}, {"subitem_title": "Quantitative Assessment of Flooded Areas Using Spectral Mixture Analysis from Satellite Optical Images and Combination Use of SAR to the 2011 Tohoku Earthquake Tsunami", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5955", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5955", "relation": {}, "relation_version_is_last": true, "title": ["光学衛星画像を用いた混合スペクトル解析に基づく浸水度の定量推定とSAR画像を組み合わせた東北地方太平洋沖地震津波への適用"], "weko_shared_id": -1}
