However, TLS underestimates the tree height due to the principle of the laser scanning. This study proposed a method for estimating tree height from the measurements of diameter at breast height and critical height (the height at the upper diameter reduced the diameter at breast height by a given ratio) using TLS. The method was verified using a large data set of Japanese cedar, Japanese cypress and Japanese larch trees across Japan. The results indicated that the proposed method enables us to estimate the tree height of the individual coniferous trees within a error of ±2 m.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(B);  研究期間：2018～2020;   課題番号：18H02244;   研究分野：森林計測学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究分担者"},{"subitem_text_value":"研究協力者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Inoue, Akio"},{"subitem_text_language":"en","subitem_text_value":"Mizoue, Nobuya"},{"subitem_text_language":"en","subitem_text_value":"Yamamoto, Kazukiyo"},{"subitem_text_language":"en","subitem_text_value":"Koshikawa, Kazuki"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部; 教授"},{"subitem_text_value":"九州大学農学研究院; 教授"},{"subitem_text_value":"名古屋大学生命農学研究科; 教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"井上, 昭夫"},{"creatorName":"イノウエ, アキオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"溝上, 展也"},{"creatorName":"ミゾウエ, ノブヤ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{"nameIdentifierURI":""}]},{"creatorNames":[{"creatorName":"山本, 一清"},{"creatorName":"ヤマモト, カズキヨ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{"nameIdentifierURI":""}]},{"creatorNames":[{"creatorName":"越河, 一樹"},{"creatorName":"コシカワ, カズキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-11-10"}],"displaytype":"detail","filename":"18H02244seika.pdf","filesize":[{"value":"332.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"18H02244seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/22147/files/18H02244seika.pdf"},"version_id":"35336d76-0ae7-4bdd-80c2-033e5e4f6c0f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"地上レーザスキャナ","subitem_subject_scheme":"Other"},{"subitem_subject":"針葉樹","subitem_subject_scheme":"Other"},{"subitem_subject":"人工林","subitem_subject_scheme":"Other"},{"subitem_subject":"樹幹形","subitem_subject_scheme":"Other"},{"subitem_subject":"森林計測","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"地上レーザ・スキャナのための森林計測学の新しい理論の構築","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地上レーザ・スキャナのための森林計測学の新しい理論の構築","subitem_title_language":"ja"},{"subitem_title":"Construction of a new theory of forest measurement for terrestrial laser scanning","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-11-10"},"publish_date":"2021-11-10","publish_status":"0","recid":"22147","relation_version_is_last":true,"title":["地上レーザ・スキャナのための森林計測学の新しい理論の構築"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-13T06:39:57.261842+00:00"}
