Then the paper discusses the precision of location information and the availability of the communication system in the forest to the forestry vehicle management system. According to the precision of location information, the precision of point positioning was examined at a fourth graded triangulation point and on a strip road, and the precision of DGPS was discussed on the basis of other researches. The precision of point positioning or DGPS is not accurate enough to develop the forestry vehicle management system. Therefore, the precision of location information must be improved using both GPS and other sensors. According to the availability of the communication system, transferring GPS data by radio system and cellular phones were examined on national roads and forest roads. Using cellular phones will enable the development of a vehicle management system because the real-time and long-distance transmission test of GPS data using cellular phones succeeded. But cellular phones cannot always be used in the forest. Therefore, utilization of the satellite communication system must also be discussed.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54118","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ARUGA, Kazuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"54119","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAKAMURA, Koji"}]},{"nameIdentifiers":[{"nameIdentifier":"54120","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FUJIWARA, Akio"}]},{"nameIdentifiers":[{"nameIdentifier":"54121","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAITO, Toshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"54122","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NITAMI, Toshio"}]},{"nameIdentifiers":[{"nameIdentifier":"54123","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAKAI, Hideo"}]},{"nameIdentifiers":[{"nameIdentifier":"54124","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOBAYASHI, Hiroshi"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科森林科学専攻"},{"subitem_text_value":"東京大学大学院農学生命科学研究科附属科学の森教育研究センター秩父演習林"},{"subitem_text_value":"Department of Forest Sciences, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"University Forest in Chichibu, University Forests, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"有賀, 一広"}],"nameIdentifiers":[{"nameIdentifier":"54111","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村, 幸児"}],"nameIdentifiers":[{"nameIdentifier":"54112","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"藤原, 章雄"}],"nameIdentifiers":[{"nameIdentifier":"54113","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"齋藤, 俊浩"}],"nameIdentifiers":[{"nameIdentifier":"54114","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"仁多見, 俊夫"}],"nameIdentifiers":[{"nameIdentifier":"54115","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"酒井, 秀夫"}],"nameIdentifiers":[{"nameIdentifier":"54116","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 洋司"}],"nameIdentifiers":[{"nameIdentifier":"54117","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-09"}],"displaytype":"detail","filename":"esrh108002.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh108002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25334/files/esrh108002.pdf"},"version_id":"fd61be7f-16d0-4653-9482-bc726bdc4d15"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"林業機械走行管理システム","subitem_subject_scheme":"Other"},{"subitem_subject":"位置情報","subitem_subject_scheme":"Other"},{"subitem_subject":"通信システム","subitem_subject_scheme":"Other"},{"subitem_subject":"Forestry Vehicle Management System","subitem_subject_scheme":"Other"},{"subitem_subject":"location information","subitem_subject_scheme":"Other"},{"subitem_subject":"communication system","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":"林業機械走行管理システムの構築に向けた位置情報通信実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"林業機械走行管理システムの構築に向けた位置情報通信実験"}]},"item_type_id":"4","owner":"1","path":["2526","2525"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25334","relation_version_is_last":true,"title":["林業機械走行管理システムの構築に向けた位置情報通信実験"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:39.050237+00:00"}
