Transect profiles of landform are considered to be self-affine because vertical and horizontal coordinates should be scaled differently, while contour lines are isotropic and self-similar. The method developed to analyze the self-affinity of curves in two-dimensional space can well express these fractal character-istics of both transect profiles and contour lines. This method is extended to analyze the three-dimensional land surfaces. The variance of elevation change Z^2, surface area S and bottom area A are measured in a number of scaling unit areas of various sizes to see whether Z^2 and A are scaled as Z^2～S^＜VZ＞ and A～S^＜VA＞. The three dimensional land surface is appeared to be self-affine with VA≅1 and 0＜VZ＜1, and the value of VZ is equivalent to the value of scaling factor H of fractional Brownian motion traces. This method of measurement well reproduces the initially introduced H value of the computer-generated fractional Brownian surfaces, and it is confirmed to work also on the real topography","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Department of Geography, Tokyo Metropolitan University"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00200173","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868710","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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":"Ouchi, Shunji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-04"}],"displaytype":"detail","filename":"20005-25-009.pdf","filesize":[{"value":"741.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20005-25-009.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2865/files/20005-25-009.pdf"},"version_id":"2b0ee625-dc02-4c4a-b63b-5212dbba9981"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"fractal geometry","subitem_subject_scheme":"Other"},{"subitem_subject":"self-affinity","subitem_subject_scheme":"Other"},{"subitem_subject":"scaling parameter","subitem_subject_scheme":"Other"},{"subitem_subject":"random surfaces","subitem_subject_scheme":"Other"},{"subitem_subject":"landform","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Self-affinity of landform and its measurement","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Self-affinity of landform and its measurement"}]},"item_type_id":"3","owner":"3","path":["548"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"2865","relation_version_is_last":true,"title":["Self-affinity of landform and its measurement"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:26:40.395463+00:00"}
