Due to the huge tsunamis occurred in the 2011 Tohoku-Oki, Japan, earthquake, more than 100 bridges located in the Pacific coast of the Tohoku region were severely damaged. In this study, the extraction of the damaged bridges in Miyagi Prefecture, Japan, was conducted by two methods using two post-event TerraSAR-X (TSX) intensity images, respectively. First, the statistical features within the outlines of the target bridges were calculated. The thresholding method of the backscatter intensity was applied to extract the damaged bridges. Then the TSX image was transformed into a binary image including water and non-water regions. The percentages of no-water regions within the bridge outlines were used to classify the washed-away and survived bridges. By comparing with the optical images and the report of field surveys, the accuracies of the proposed two methods and the influence of the shooting date were investigated.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1109/IGARSS.2019.8898247"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Wen Liu", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Fumio Yamazaki", "creatorNameLang": "en"}]}]}, "item_title": "Bridge Damage Assessment Using Single Post-Event Terrasar-X Image", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Bridge Damage Assessment Using Single Post-Event Terrasar-X Image", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/2949", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "2949", "relation": {}, "relation_version_is_last": true, "title": ["Bridge Damage Assessment Using Single Post-Event Terrasar-X Image"], "weko_shared_id": -1}
