Japanese airborne Pi-SAR-L2 and PiSAR-L data were used in this analysis. Several L-band full polarimetric parameters, including backscattering coefficient (σ deg), coherence between two polarimetric states, four-component decomposition parameters (double-bounce/volume/surface/helix scattering), and eigenvalue decomposition parameters (entropy/α/anisotropy), were calculated to determine the most appropriate parameters for detecting landslide areas. The change in land cover from forest before the disaster to bare soil after the disaster was detected well by α, and coherence between HH and VV. Observational data from the bottom to the top of the landslide detected the landslide well, whereas observations from the opposite sides were not as useful, indicating that a smaller local incident angle is better to distinguish landslide and forested areas. Soil from the landslide intruded into the urban areas; however, none of the full polarimetric parameters showed any significant differences between the landslide-affected urban areas after the disaster and unaffected areas before the disaster.","subitem_description_type":"Other"}]},"item_7_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1610021000","subitem_description_type":"Other"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Multidisciplinary Digital Publishing Institute"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.3390/rs8040282"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.3390/rs8040282","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2072-4292","subitem_source_identifier_type":"ISSN"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構地球観測研究センター(JAXA)(EORC)"},{"subitem_text_value":"宇宙航空研究開発機構地球観測研究センター(JAXA)(EORC)"},{"subitem_text_value":"宇宙航空研究開発機構地球観測研究センター(JAXA)(EORC): 東京電機大学"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Earth Observation Research Center, Japan Aerospace Exploration Agency(JAXA)(EORC)"},{"subitem_text_language":"en","subitem_text_value":"Earth Observation Research Center, Japan Aerospace Exploration Agency(JAXA)(EORC)"},{"subitem_text_language":"en","subitem_text_value":"Earth Observation Research Center, Japan Aerospace Exploration Agency(JAXA)(EORC): Tokyo Denki University"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡邉, 学"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Thapa, Rajesh Bahadur"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"島田, 政信"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Manabu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Thapa, Rajesh Bahadur","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimada, Masanobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"polarimetry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"disaster","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"L-band SAR","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Pi-SAR-L2 Observation of the Landslide Caused by Typhoon Wipha on Izu Oshima Island","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pi-SAR-L2 Observation of the Landslide Caused by Typhoon Wipha on Izu Oshima Island","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-05-31"},"publish_date":"2016-05-31","publish_status":"0","recid":"22651","relation_version_is_last":true,"title":["Pi-SAR-L2 Observation of the Landslide Caused by Typhoon Wipha on Izu Oshima Island"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:17:36.491250+00:00"}
