In order to improve AFCS estimates, the present study evaluates the potential of high-resolution ALOS/PALSAR mosaics data in the tropical forests in central Sumatra. The study region with AFCS range of 1 to 334 Mg ha(exp -1) consists of natural and plantation forests. Field measurements of AFCS were carried out in 87 plots. Various textures of dual polarized mosaics data for the year 2009 and 2010 were computed and assessed their potential for estimating AFCS applying regression modelling. R(exp 2), p-value, variable inflation factor, and root mean square errors (RMSE) were examined. Potential models were cross validated by leave- one-out (LOO) method. The result indicates that simple textures analysis in PALSAR mosaics increases potential of AFCS estimation and reduces errors to 30.5 Mg ha(exp -1). The method and models presented in this study can be a low cost wall-to-wall forest carbon mapping with high level of accuracy in tropical forests in Southeast Asia where other methods are still rare.","subitem_description_type":"Other"}]},"item_5_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"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AC1600054000","subitem_description_type":"Other"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Electrical and Electronics Engineers(IEEE)"}]},"item_5_relation_23":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"978-1-46737-298-5","subitem_relation_type_select":"ISBN"}}]},"item_5_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1109/APSAR.2015.7306295"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1109/APSAR.2015.7306295","subitem_relation_type_select":"DOI"}}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構地球観測研究センター(JAXA)(EORC)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Eerth Observation Research Center, Japan Aerospace Exploration Agency (JAXA)(EORC)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Thapa, Rajesh Bahadur"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡邉, 学"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"本岡, 毅"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"島田, 政信"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Thapa, Rajesh Bahadur","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Manabu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Motohka, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimada, Masanobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"AFCS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Biomass modeling","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"REDD+","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Natural forest","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Plantation forest","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Texture analysis of PALSAR mosaics for forests carbon stock estimation in central Sumatra","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Texture analysis of PALSAR mosaics for forests carbon stock estimation in central Sumatra","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-08-15"},"publish_date":"2016-08-15","publish_status":"0","recid":"38792","relation_version_is_last":true,"title":["Texture analysis of PALSAR mosaics for forests carbon stock estimation in central Sumatra"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:35:27.231233+00:00"}
