By the field investigation the subsidence of sinkhole type can be detected well, while the subsidence of trough type could not be identified due to its very gentle and gradual settling of ground deformation. Conversely, interferometric SAR measurement is more powerful tools to detect subtle settlements of the overlying ground surface. For effective monitoring over wide areas we applied small baseline subset (SBAS) technique using 21 ALOS PALSAR data of Gangwon province during the period from October 2006 to June 2010. Fifty-five differential interferograms with a perpendicular baseline less than 1100m were constructed. As a result, we obtained a mean deformation map and time evolution of deformation at each points along LOS (Line-Of-Sight) direction over 70km × 70km wide areas. Two main subsiding areas, which are not recognized before, were clearly revealed by this map, and the continuous subsidence at a rate of 4.5cm/yr, for a total subsidence of 20 cm over 1334 day was observed at the most significant subsiding point. The RMSE with respect to linear deformation is about 1cm in overall area, and 2-3cm in densely vegetated area. Overlaying deformation map with underground mine map shows good agreement in spatial extent. Therefore, we expect that subsidence is mainly caused by mining activities in the study area.","subitem_description_type":"Other"}]},"item_3_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"},{"subitem_description":"形態: DVD-ROM1枚","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"},{"subitem_description":"Note: One DVD-ROM","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0065135111","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-11-007E","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構地球観測研究センター (JAXA)(EORC)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Earth Observation Research Center, Japan Aerospace Exploration Agency (JAXA)(EORC)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Geoinformation Engineering, Sejong University"},{"subitem_text_language":"en","subitem_text_value":"Department of Geoinformation Engineering, Sejong University"},{"subitem_text_language":"en","subitem_text_value":"Department of Earth System Sciences, Yonsei University"},{"subitem_text_language":"en","subitem_text_value":"Department of Geoinformation Engineering, Sejong University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kim, Sang-Wan","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Cho, Min-Ji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Jo, Min-Jeong","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Park, Hyuck-Jin","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"65135111.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"65135111.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4581/files/65135111.pdf"},"version_id":"d0b2fbb9-a3be-40a0-a2c4-2d807c6ced64"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"GROUND SUBSIDENCE MONITORING BY SBAS ANALYSIS IN MINING AREAS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"GROUND SUBSIDENCE MONITORING BY SBAS ANALYSIS IN MINING AREAS","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["914","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4581","relation_version_is_last":true,"title":["GROUND SUBSIDENCE MONITORING BY SBAS ANALYSIS IN MINING AREAS"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:36:09.829479+00:00"}
