Therefore, using drones, we investigated the influence of the Kumamoto earthquake on the surface of farmlands.  We calculated a three-dimensional model by performing SfM（Structure from Motion）-MVS （Multi View Stereo）processing of the drone aerial images and performed DSM（Digital Surface Model）by combining the altitude levels obtained by the ground-survey results. After comparison of the results with the airplane laser-survey results, the quantity of unevenness （difference from the mean altitude level of the farmland ground）measured by the drones exhibited a high precision; thus, a meaningful difference was not observed. On the other hand, the measurement cost of the drone survey was approximately one-third that of the airplane laser survey. In addition, quick mobile observation was made possible. It was concluded that the quantity of unevenness measured by the drones be able to evaluation. Furthermore, we investigated the cause of the wavy surface confirmed by the drone observation. As a result, the reentrant of the unevenness accorded with that of the creeks of the aerial photograph obtained in 1962. We reveal that the 2016 Kumamoto earthquake sank the creek part before the infrastructure maintenance.\n","subitem_description_type":"Abstract"},{"subitem_description":"地震による被災農地圃場では，被害状況により，復旧に向けた対策が異なってくる。このため，熊本地震が農地の地表に及ぼした影響についてドローンを用いて調査した。ドローン空撮画像に SfM・MVS 処理を行うことで 3 次元モデルを作成し，国土地理院の地理院地図の座標値と地上における簡易測量結果を組み合わせることで，DSMを作成した。その結果， 圃場の不陸量（ほ場の平均標高値からの差）や亀裂が計測・評価可能であることを明らかにした。ドローンで計測した不陸量は，航空機 LiDAR 測量と比較したところ，有意な差が認められない高い精度を有していた。一方，計測コストは航空機 LiDAR 測量の約 1/3 であり， 加えて，迅速に機動的な観測が可能という利点がある。さらに，ドローン観測により確認された規則的な地表面の不陸について原因を探ったところ，不陸の凹部が 1962 年撮影の航空写真の水路部分と一致しており，熊本地震により圃場基盤整備前の水路の埋め立て部分が沈下したことを明らかにした。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00002294","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人 農業・食品産業技術総合研究機構"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00002294","subitem_relation_type_select":"DOI"}}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石塚, 直樹"},{"creatorName":"イシツカ, ナオキ","creatorNameLang":"ja-Kana"},{"creatorName":"ISHITSUKA, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"岩崎, 亘典","creatorNameLang":"ja"},{"creatorName":"IWASAKI, Nobusuke","creatorNameLang":"en"},{"creatorName":"岩﨑, 亘典","creatorNameLang":"ja"},{"creatorName":"イワサキ, ノブスケ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{},{}],"givenNames":[{},{},{},{}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"坂本, 利弘"},{"creatorName":"サカモト, トシヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"SAKAMOTO, Toshihiro","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":"2019-03-25"}],"displaytype":"detail","filename":"Mem-KARC_no95_p3-9.pdf","filesize":[{"value":"987.2 kB"}],"format":"application/pdf","license_note":"© 国立研究開発法人 農業・食品産業技術総合研究機構\nNational Agriculture and Food Research Organization, Japan\n","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Mem-KARC_no95_p3-9.pdf ","url":"https://repository.naro.go.jp/record/2391/files/Mem-KARC_no95_p3-9.pdf"},"version_id":"94d55fca-4e18-4a15-9686-17c2c71dbc97"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"熊本地震","subitem_subject_scheme":"Other"},{"subitem_subject":"ドローン","subitem_subject_scheme":"Other"},{"subitem_subject":"不陸","subitem_subject_scheme":"Other"},{"subitem_subject":"SfM・MVS","subitem_subject_scheme":"Other"},{"subitem_subject":"2016 Kumamoto earthquake","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Drone","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Unevenness","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"SfM-MVS","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ドローンを用いた平成 28 年熊本地震が農地の地表に及ぼした影響の調査－３次元モデリング解析を活用した不陸評価－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ドローンを用いた平成 28 年熊本地震が農地の地表に及ぼした影響の調査－３次元モデリング解析を活用した不陸評価－"},{"subitem_title":"Investigation Using Drones on the Influence of the 2016 Kumamoto Earthquake on the Surface of Farmlands","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["373","461"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-25"},"publish_date":"2019-03-25","publish_status":"0","recid":"2391","relation_version_is_last":true,"title":["ドローンを用いた平成 28 年熊本地震が農地の地表に及ぼした影響の調査－３次元モデリング解析を活用した不陸評価－"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2024-02-03T14:29:21.497471+00:00"}
