We introduce a novel method based on a customized set of normalized difference Spectral Index Ratios (SIRs), incorporating multiple bands, to improve the accuracy of land-cover mapping in the Antarctic. Most recently available WV-2 data are classified into land-cover surfaces such as snow/ice, water bodies, and landmass using the customized normalized difference SIRs. A novel multi-fold methodology is used to evaluate the effect of pan-sharpening algorithms on spectral characteristics of satellite data, and on subsequent land-cover mapping using an array of SIRs. A set of existing pan-sharpening algorithms was implemented in order to fuse PAN with MSI data, followed by estimation of multiple SIRs to extract target land-cover classes. These algorithms were compared on the basis of their effectiveness in extracting target classes using a defined set of SIRs. Our results indicate that the use of 8-band WV-2, customized SIRs, and appropriate pan-sharpening can greatly improve the extraction of land-cover information.", "subitem_description_type": "Abstract"}]}, "item_10001_description_6": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "　 本研究は、8バンド高解像度WorldView-2衛星(WV-2)のパンクロマティック(PAN)およびマルチスペクトル画像(MSII)データによる、極域の地理空間情報の抽出の可能性について評価した。南極域における土地被覆マッピングの精度を改善するため、専用の正規化差分スペクトル指数比（SIRs）に基づいた新たな方法を導入した。SIRsにより、入手可能なWV-2のデータを用いて、陸域表層を雪/氷、水域および露岩等の分類を行った。衛星データのスペクトル特性と、関連するSIRsを用いた土地被覆マッピングにおける、パンシャープン・アルゴリズムの効果を評価するため、新たな多様な方法論が用いられた。MSIデータとPANを合成するために、現存するパンシャープン・アルゴリズムが適応され、続いてその結果から対象となる土地被覆種類を抽出するための複数のSIRsが見積もられた。これらのアルゴリズムは、定義したSIRsを用いた対象の種類を抽出するための有効性を元に比較された。我々の結果により、8バンドWV-2、専用のSIRs、および適切なパンシャープン処理によって、土地被覆情報の抽出が大きく改善される事が明らかになった。", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "国立極地研究所"}]}, "item_10001_relation_12": {"attribute_name": "論文ID（NAID）", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "110009575379", "subitem_relation_type_select": "NAID"}}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "10.1016/j.polar.2012.12.002"}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.1016/j.polar.2012.12.002", "subitem_relation_type_select": "DOI"}}]}, "item_10001_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA12240481", "subitem_source_identifier_type": "NCID"}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "18739652", "subitem_source_identifier_type": "ISSN"}]}, "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": "Jawak, Shridhar D."}], "nameIdentifiers": [{"nameIdentifier": "18501", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Luis, Alvarinho J."}], "nameIdentifiers": [{"nameIdentifier": "18502", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Jawak, Shridhar D.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "18503", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Luis, Alvarinho J.", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "18504", "nameIdentifierScheme": "WEKO"}]}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Pan-sharpening", "subitem_subject_scheme": "Other"}, {"subitem_subject": "WorldView-2", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Index ratios", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Land-cover", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Pan-sharpening", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "WorldView-2", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Index ratios", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Land-cover", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "A Spectral Index Ratio-based Antarctic Land-cover Mapping Using Hyperspatial 8-band WorldView-2 Imager", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "A Spectral Index Ratio-based Antarctic Land-cover Mapping Using Hyperspatial 8-band WorldView-2 Imager"}, {"subitem_title": "A Spectral Index Ratio-based Antarctic Land-cover Mapping Using Hyperspatial 8-band WorldView-2 Imager", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "27", "path": ["1344"], "permalink_uri": "https://nipr.repo.nii.ac.jp/records/10123", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-10-16"}, "publish_date": "2014-10-16", "publish_status": "0", "recid": "10123", "relation": {}, "relation_version_is_last": true, "title": ["A Spectral Index Ratio-based Antarctic Land-cover Mapping Using Hyperspatial 8-band WorldView-2 Imager"], "weko_shared_id": 27}
