The rice acreage is surveyed every year by the Statistical Information Office under the Ministry of Agriculture, Forestry and Fishery ,requiring a great deal of labor. In this paper, the rice acreage around Nagaoka city area is estimated using ERS-2 SAR data acquired on May and June and Landsat TM data acquired on August. SAR data are obtained at the time of rice planting season and about one month after it, and TM data are just before harvesting during the rice growing season. As SAR can observe through- clouds, SAR data are can be obtained at the rice planting season, which falls at the rainy season. The rice acreage estimated by satellite data was compared with that surveyed by Niigata Statistical Information Office. The error was small for the flat-terrained area (3.6%) , but large for the hilly area (9.1%) . The reason for this is considered to be that SAR data were affected by the incidence angle to the ground and the incidence angle may be different in the hilly area. It is found that SAR data acquired at rice planting season and optical sensor data acquired during rice growing season are effective to estimate the rice .acreage for the flat area. Hereafter it is necessary to study for improving the accuracy for the hilly area such as correction processes of the incidence angle.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "3414", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "MUKAI, Yukio"}]}, {"nameIdentifiers": [{"nameIdentifier": "3415", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "RIKIMARU, Atsushi"}]}, {"nameIdentifiers": [{"nameIdentifier": "3416", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "TAKAHASHI, Kazuyoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "3417", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "SUGAWARA, Kouhei"}]}]}, "item_4_publisher_35": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "長岡技術科学大学"}]}, "item_4_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00177120", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0388-5631", "subitem_source_identifier_type": "ISSN"}]}, "item_4_text_4": {"attribute_name": "著者所属", "attribute_value_mlt": [{"subitem_text_value": "長岡技術科学大学環境・建設系"}, {"subitem_text_value": "長岡技術科学大学環境・建設系"}, {"subitem_text_value": "長岡技術科学大学環境・建設系"}, {"subitem_text_value": "(株)富士通新潟システムズ"}]}, "item_4_version_type_18": {"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": "向井, 幸男"}], "nameIdentifiers": [{"nameIdentifier": "3410", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "力丸, 厚"}], "nameIdentifiers": [{"nameIdentifier": "3411", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "高橋, 一義"}], "nameIdentifiers": [{"nameIdentifier": "3412", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "菅原, 航平"}], "nameIdentifiers": [{"nameIdentifier": "3413", "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": "2018-08-03"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "K24_3.pdf", "filesize": [{"value": "80.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 80400.0, "url": {"label": "K24_3.pdf", "url": "https://nagaokaut.repo.nii.ac.jp/record/704/files/K24_3.pdf"}, "version_id": "95dee808-a1d2-4fc5-ab0f-03d95196cc03"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Satellite data", "subitem_subject_scheme": "Other"}, {"subitem_subject": "SAR and Optical sensor", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Rice acreage estimation", "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": "衛星搭載合成開口レーダと光学センサーによる長岡市周辺地域の稲の作付面積推定", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "衛星搭載合成開口レーダと光学センサーによる長岡市周辺地域の稲の作付面積推定"}]}, "item_type_id": "4", "owner": "2", "path": ["63"], "permalink_uri": "http://hdl.handle.net/10649/605", "pubdate": {"attribute_name": "公開日", "attribute_value": "2011-02-15"}, "publish_date": "2011-02-15", "publish_status": "0", "recid": "704", "relation": {}, "relation_version_is_last": true, "title": ["衛星搭載合成開口レーダと光学センサーによる長岡市周辺地域の稲の作付面積推定"], "weko_shared_id": -1}
