NSW Physiography Category - Fuzzy Extent Line
收藏资源简介:
Export Data Access APINSW Physiography Category - Fuzzy Extent LinePlease NoteWGS 84 service aligned to GDA94This dataset has spatial reference [WGS 84 ≈ GDA94] which may result in misalignments when viewed in GDA2020 environments. A similar service with a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS 84 ≈ GDA2020 environments.In due course, and allowing time for user feedback and testing, it is intended that the original service name will adopt the new 'multiCRS' functionality.Metadata Portal Metadata InformationContent TitleNSW Physiography Category - Fuzzy Extent LineContent TypeHosted Feature LayerDescriptionFuzzy Extent Line is a line feature class representing the approximate centreline of formally named landforms that have relatively indistinct name extent.\nData included in Fuzzy Extent Line includes:Beach - The gently sloping shore which is washed by waves or tides, especially the parts covered by sand or pebbles.Dune Like - A named dune-like landform, includes GNB designations: Dune, Sandhill & Sandridge.General Locality - A formally named general place or locality of indistinct extent not readily classified by a more specific feature classification.Range Like - A named range-like landform., includes GNB designations: Mountain Range, Range, Ridge & Spur.Valley Like - Named valley-like landform, includes GNB designations: Amphitheatre, Basin, Bend, Canyon, Chasm, Crater, Cutting, Depression, Glen, Gorge, Gulf, Gullies, Hole, Ravine, Sink & Valley.Initial Publication Date07/02/2020Data Currency01/01/3000Data Update FrequencyOtherContent SourceData provider filesFile TypeESRI File Geodatabase (*.gdb)Attribution© State of New South Wales (Spatial Services, a business unit of the Department of Customer Service NSW). For current information go to spatial.nsw.gov.auData Theme, Classification or Relationship to other DatasetsNSW Physiography Category of the Foundation Spatial Data Framework (FSDF)AccuracyThe dataset maintains a positional relationship to, and alignment with, a range of themes from the NSW FSDF including, transport, imagery, positioning, water and land cover. This dataset was captured by digitising the best available cadastral mapping at a variety of scales and accuracies, ranging from 1:500 to 1:250 000 according to the National Mapping Council of Australia, Standards of Map Accuracy (1975). Therefore, the position of the feature instance will be within 0.5mm at map scale for 90% of the well-defined points. That is, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = 25m and 1:100000 = 50m. A program to upgrade the spatial location and accuracy of data is ongoing.Spatial Reference System (dataset)GDA94Spatial Reference System (web service)EPSG:3857WGS84 Equivalent ToGDA94Spatial ExtentFull StateContent LineageFor additional information, please contact us via the Spatial Services Customer HubData ClassificationUnclassifiedData Access PolicyOpenData QualityFor additional information, please contact us via the Spatial Services Customer HubTerms and ConditionsCreative CommonsStandard and SpecificationOpen Geospatial Consortium (OGC) implemented and compatible for consumption by common GIS platforms.

导出数据访问:APINSW 地貌类别-模糊范围线 请注意 本服务基于世界大地测量系统1984(WGS 84)坐标系对齐至澳大利亚大地测量系统1994(GDA94)。 本数据集的空间参考为[WGS 84 ≈ GDA94],在GDA2020环境中查看时可能会出现坐标偏移。另有带“multiCRS”后缀的同类服务,可支持GDA2020、GDA94以及WGS 84 ≈ GDA2020坐标系环境。 后续将预留充足时间收集用户反馈并开展测试,计划将原服务名称升级为支持multiCRS功能的版本。 元数据门户元数据信息 内容标题:NSW 地貌类别-模糊范围线 内容类型:托管要素图层(Hosted Feature Layer) 描述: 模糊范围线(Fuzzy Extent Line)为线状要素类,用于表示正式命名但范围相对模糊的地貌的近似中心线。 模糊范围线包含以下数据类型: - 滩涂(Beach):受波浪或潮汐冲刷的缓坡海岸,尤指覆盖沙或砾石的区域。 - 类沙丘地貌(Dune Like):命名的类沙丘地貌,包含GNB分类项:沙丘(Dune)、沙岗(Sandhill)与沙脊(Sandridge)。 - 通用区位(General Locality):正式命名但范围模糊、无法归入更具体要素类别的通用地点或区位。 - 类山脉地貌(Range Like):命名的类山脉地貌,包含GNB分类项:山脉(Mountain Range)、山岭(Range)、山脊(Ridge)与支脉(Spur)。 - 类河谷地貌(Valley Like):命名的类河谷地貌,包含GNB分类项:圆形山谷(Amphitheatre)、盆地(Basin)、河湾(Bend)、峡谷(Canyon)、深壑(Chasm)、火山口(Crater)、路堑(Cutting)、洼地(Depression)、幽谷(Glen)、溪谷(Gorge)、海湾(Gulf)、冲沟(Gullies)、洞穴(Hole)、沟壑(Ravine)、落水洞(Sink)与河谷(Valley)。 首次发布日期:2020年2月7日 数据现势性:3000年1月1日 数据更新频率:其他 数据来源:数据提供方文件 文件类型:ESRI 文件地理数据库(*.gdb) 版权标注:© 新南威尔士州政府(空间服务部,新南威尔士州客户服务厅下属业务单元)。如需获取最新信息,请访问 spatial.nsw.gov.au 数据主题、分类及与其他数据集的关联关系: 属于基础空间数据框架(Foundation Spatial Data Framework,FSDF)的NSW地貌类别。 精度说明: 本数据集与新南威尔士州基础空间数据框架的多个主题(包括交通、影像、定位、水系与土地覆被)保持空间位置关联与对齐。本数据集通过数字化现有最优地籍测绘数据生成,比例尺与精度覆盖1:500至1:250000,符合澳大利亚国家测绘委员会1975年发布的《地图精度标准》。因此,90%的明确点位在对应比例尺下的位置误差不超过0.5毫米:即1:500比例尺对应0.25米,1:2000比例尺对应1米,1:4000比例尺对应2米,1:25000比例尺对应12.5米,1:50000比例尺对应25米,1:100000比例尺对应50米。 目前正在推进项目以升级本数据集的空间位置与精度。 空间参考系统(数据集):GDA94 空间参考系统(Web服务):EPSG:3857 等效WGS84坐标系:GDA94 空间范围:全州范围 数据谱系:如需更多信息,请通过空间服务客户中心联系我们。 数据分类:非保密 数据访问政策:开放 数据质量:如需更多信息,请通过空间服务客户中心联系我们。 条款与条件:知识共享(Creative Commons) 标准与规范:符合开放地理空间联盟(Open Geospatial Consortium,OGC)标准,可兼容通用GIS平台读取。可根据客户端使用需求或场景,提供缓存或非缓存服务。 数据托管方:DCS 空间服务部 地址:澳大利亚新南威尔士州巴瑟斯特市全景大道346号,邮编2795 联系人:请通过空间服务客户中心联系我们 数据聚合方:DCS 空间服务部 地址:澳大利亚新南威尔士州巴瑟斯特市全景大道346号,邮编2795 数据分发方:DCS 空间服务部 地址:澳大利亚新南威尔士州巴瑟斯特市全景大道346号,邮编2795 附加支持信息 数据字典:TRIM编号
