Ground control points (GCPs) were added to the orthophotos by visually checking the image. Mapping of GCPs was approximate, due to the lack of necessary geographical information. It may be difficult to use these data to develop accurate maps for analyzing the spatial distribution of plant and vegetation, because there may be considerable errors in the geographical positions indicated in the orthophotos. However, these maps will provide a good basis for comparison with aerial photos generated by the next expedition to this island, allowing an analysis of changes in spatial vegetation patterns. The next expedition is also expected to be able to document the position of the GCPs on the ground and/or use a drone mounted GNSS (Global Navigation Satellite System).","subitem_description_type":"Abstract"}]},"item_16_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"postprint","subitem_description_type":"Other"}]},"item_16_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"首都大学東京小笠原研究委員会"}]},"item_16_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00032332","subitem_source_identifier_type":"NCID"}]},"item_16_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868176","subitem_source_identifier_type":"ISSN"}]},"item_16_version_type_16":{"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":"加藤, 英寿"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"朱宮, 丈晴"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山崎, 敦基"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-13"}],"displaytype":"detail","filename":"20001-044-006.pdf","filesize":[{"value":"997.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20001-044-006.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/7251/files/20001-044-006.pdf"},"version_id":"e890d191-e572-4355-b589-b99aa7f12993"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ドローン","subitem_subject_scheme":"Other"},{"subitem_subject":"空中映像","subitem_subject_scheme":"Other"},{"subitem_subject":"オルソ画像","subitem_subject_scheme":"Other"},{"subitem_subject":"幾何補正","subitem_subject_scheme":"Other"},{"subitem_subject":"分布図","subitem_subject_scheme":"Other"},{"subitem_subject":"Aerial image","subitem_subject_scheme":"Other"},{"subitem_subject":"Distribution map","subitem_subject_scheme":"Other"},{"subitem_subject":"Drone","subitem_subject_scheme":"Other"},{"subitem_subject":"Geometric correction","subitem_subject_scheme":"Other"},{"subitem_subject":"Orthophoto","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":"小型UAVによる空撮映像を用いた南硫黄島の植物分布・植生図作成の試み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"小型UAVによる空撮映像を用いた南硫黄島の植物分布・植生図作成の試み"}]},"item_type_id":"16","owner":"3","path":["1642"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-15"},"publish_date":"2019-03-15","publish_status":"0","recid":"7251","relation_version_is_last":true,"title":["小型UAVによる空撮映像を用いた南硫黄島の植物分布・植生図作成の試み"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T16:19:48.764825+00:00"}
