The study area is Yokohama City, Japan, an area of 437.4 km<sup>2</sup>. An allometric equation was developed from field measurement data to convert canopy height measured by airborne LiDAR to biomass, and then a map of aboveground biomass (AGB) at 5 m resolution was produced. After validation, the estimation of AGB had a root mean square error of 60.6 Mg ha<sup>-1</sup> and an average relative error of 38.7%. The total forest AGB in Yokohama was estimated as 913,450 Mg. The results suggest that airborne LiDAR is suitable for developing a reliable forest biomass map, even for scattered forests in urban area.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人 日本写真測量学会","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Society of Photogrammetry and Remote Sensing","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.4287/jsprs.52.306"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-5844","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"林 真智","creatorNameLang":"ja"},{"creatorName":"HAYASHI Masato","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"山形 与志樹","creatorNameLang":"ja"},{"creatorName":"YAMAGATA Yoshiki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"平 春","creatorNameLang":"ja"},{"creatorName":"BORJIGIN Habura","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"哈斯 巴干","creatorNameLang":"ja"},{"creatorName":"BAGAN Hasi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"鈴木 力英","creatorNameLang":"ja"},{"creatorName":"SUZUKI Rikie","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"三枝 信子","creatorNameLang":"ja"},{"creatorName":"SAIGUSA Nobuko","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"航空機LiDARデータを利用した横浜市の森林バイオマス地図の作成","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"航空機LiDARデータを利用した横浜市の森林バイオマス地図の作成","subitem_title_language":"ja"},{"subitem_title":"Forest biomass mapping with airborne LiDAR in Yokohama City","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"5818","relation_version_is_last":true,"title":["航空機LiDARデータを利用した横浜市の森林バイオマス地図の作成"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T09:30:49.080614+00:00"}
