NSW Physiography Category - Distinctive Land Surface (DLS) Point

Export Data Access APINSW Physiography Category - Distinctive Land Surface (DLS) PointPlease NoteWGS 84 service aligned to GDA94This\n dataset has spatial reference [WGS 84 ≈ GDA94] which may result in \nmisalignments when viewed in GDA2020 environments. A similar service \nwith a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 \nand WGS 84 ≈ GDA2020 environments.In due course, and allowing time \nfor user feedback and testing, it is intended that the original service \nname will adopt the new 'multiCRS' functionality.Metadata Portal Metadata InformationContent TitleNSW Physiography Category - Distinctive Land Surface (DLS) PointContent TypeHosted Feature LayerDescriptionDistinctive Land Surface or DLS Point is a point feature class defining Distinctive Land Surface features of discrete extent.Included in the Distinctive land Surface Point are:Reef - A ridge, usually of rock or coral, lying near the surface of the sea, which may be visible at low tide, but is usually covered by water.Initial Publication Date07/02/2020Data Currency01/01/3000Data Update FrequencyOtherContent SourceData provider filesFile TypeESRI File Geodatabase (*.gdb)Attribution©\n State of New South Wales (Spatial Services, a business unit of the \nDepartment 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\n dataset maintains a positional relationship to, and alignment with, a \nrange of themes from the NSW FSDF including, transport, imagery, \npositioning, water and land cover. This dataset was captured by \ndigitising the best available cadastral mapping at a variety of scales \nand accuracies, ranging from 1:500 to 1:250 000 according to the \nNational Mapping Council of Australia, Standards of Map Accuracy (1975).\n Therefore, the position of the feature instance will be within 0.5mm at\n map scale for 90% of the well-defined points. That is, 1:500 = 0.25m, \n1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = 25m and 1:100000 = \n50m. A program to upgrade the spatial location and accuracy of data is \nongoing.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\n Geospatial Consortium (OGC) implemented and compatible for consumption \nby common GIS platforms.

导出数据访问 APINSW 地貌类别——标志性地表（Distinctive Land Surface, DLS）点位
请注意：本服务基于世界大地测量系统1984（WGS 84）与澳大利亚大地基准1994（GDA94）对齐。本数据集的空间参考为【WGS 84 ≈ GDA94】，在澳大利亚大地基准2020（GDA2020）环境中查看时可能出现坐标偏移。另有带"multiCRS"后缀的同类服务，可支持GDA2020、GDA94以及WGS 84 ≈ GDA2020环境。在完成用户反馈收集与测试后，原服务将升级为支持该多坐标参考系统（multiCRS）功能。

数据主题、分类及与其他数据集的关联：基础空间数据框架（Foundation Spatial Data Framework, FSDF）中新南威尔士州地貌类别
精度说明：本数据集与新南威尔士州基础空间数据框架（FSDF）中的交通、影像、定位、水系及土地覆被等多类主题数据保持空间位置关联与对齐。本数据集通过数字化不同比例尺与精度的现有最佳地籍测绘成果生成，比例尺范围为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》。据此，90%的明确点位的坐标误差在对应比例尺下不超过0.5mm：即1:500比例尺对应0.25米、1:2000对应1米、1:4000对应2米、1:25000对应12.5米、1:50000对应25米、1:100000对应50米。目前本数据集的空间位置与精度升级工作正在推进中。
