Export Data Access APINSW Positioning Theme - Survey Mark GDA94 multiCRSMultiCRS service - supporting requests in multiple Coordinate Reference Systems - Information SheetNote: GDA94 coordinates for NSW survey marks are no longer maintained. This data has been superseded by NSW Positioning Theme Survey Mark GDA2020 multiCRS or NSW Positioning Theme - Survey Mark GDA2020A new series of ‘multiCRS’ web services have been published to support GDA2020. These new ‘multiCRS’ services:· have a spatial reference of GDA2020· support alignment with GDA2020, GDA94 or [WGS 84-aligned-to-GDA2020] GIS environments,using built-in server-side transformations:o GDA94 < NTv2-CPD > GDA2020o GDA94 < NTv2-CPD > WGS 84 aligned to GDA2020o GDA2020 < NULL > WGS 84 aligned to GDA2020 Note: ESRI software will automatically align by transforming from the sourceSpatialReference (GDA94). Other software may need to set client-side transformations from the SpatialReference (GDA2020). Note: Client-side transformation(s) can be used to over-ride these default transformations.The original [WGS 84-aligned-to-GDA2020] is still available, without the ‘multiCRS’ suffix. In due course, and allowing time for user feedback and testing, it is intended that the original service name will adopt this new 'multiCRS' functionality.Please note that SCIMS Online is the official option for obtaining state control survey data for cadastral surveys as it offers legal traceability. SCIMS online is accessible via the Spatial portal.Metadata Portal Metadata InformationContent TitleNSW Positioning Theme - Survey Mark GDA94 multiCRSContent TypeHosted Feature LayerDescriptionThis service provides GDA94 coordinates, heights and related information for NSW survey marks that form the official State control survey network (as reported in SCIMS). This service controls the precision of numerical output in a manner that mirrors SCIMS Online available through the Spatial Services Portal.The web service provides a wealth of data on each mark, including:mark type (Permanent Mark, State Survey Mark, etc.) mark number horizontal coordinates and their accuracy (class and order) heights and their accuracy (class and order) status of the mark (destroyed, restricted access, etc.) The mark type is represented using various shapes and the accuracy of the mark (both vertical and horizontal) is communicated by the colour. This web service allows users to easily integrate survey control mark data from SCIMS into Open Geospatial Consortium (OGC) compliant spatial platforms and applications. Data provided by the NSW Survey Mark web service can be used in a variety of engineering and surveying applications, including but not limited to: cadastral survey planning flood studies and hydrographic modelling infrastructure developmentsite calibration at construction sites elevation modelling preservation of survey infrastructure.The NSW Survey Mark web service gives users an alternative method to access state control survey data that can be incorporated into their GIS package without needing to log into SCIMS Online.Please note that SCIMS Online is the official option for obtaining state control survey data for cadastral surveys as it offers legal traceability.

导出数据访问APINSW定位主题——测量标志GDA94多坐标系("multiCRS")服务:支持多坐标系请求——信息表 注:新南威尔士州(NSW)测量标志的GDA94坐标系坐标已不再维护,该数据集已由《NSW定位主题——测量标志GDA2020多坐标系("multiCRS")》或《NSW定位主题——测量标志GDA2020》替代。 现已发布一系列新型多坐标系("multiCRS")网络服务以支持GDA2020基准。这些新型多坐标系服务具备以下特性: · 空间参考系为GDA2020 · 支持与GDA2020、GDA94或【与GDA2020对齐的WGS84】GIS环境对接,内置服务端坐标转换功能,包括: o GDA94 < NTv2-CPD > GDA2020 o GDA94 < NTv2-CPD > 与GDA2020对齐的WGS84 o GDA2020 < NULL > 与GDA2020对齐的WGS84 注:ESRI软件将自动基于源空间参考系(GDA94)进行坐标转换以实现对齐。其他软件则可能需要从空间参考系(GDA2020)配置客户端坐标转换。 注意:可使用客户端坐标转换覆盖上述默认转换规则。 原【与GDA2020对齐的WGS84】服务仍可访问,其名称不带"multiCRS"后缀。在预留足够时间收集用户反馈并完成测试后,官方计划将原服务名称升级为该新型多坐标系功能版本。 请注意,SCIMS在线平台(SCIMS Online)是获取地籍测量所需国家控制测量数据的官方途径,因其具备法律溯源性。用户可通过空间门户(Spatial portal)访问SCIMS在线平台。 ### 元数据(Metadata) #### 内容标题 NSW定位主题——测量标志GDA94多坐标系("multiCRS") #### 内容类型 托管要素图层(Hosted Feature Layer) #### 服务描述 本服务为构成新南威尔士州官方国家控制测量网络的测量标志提供GDA94坐标系坐标、高程及相关信息(数据源自SCIMS平台)。本服务的数值输出精度规范与通过空间服务门户(Spatial Services Portal)提供的SCIMS在线平台保持一致。 本网络服务为每个测量标志提供丰富的数据信息,包括: · 标志类型(永久标志、国家测量标志等) · 标志编号 · 平面坐标及其精度等级(类别与等级) · 高程及其精度等级(类别与等级) · 标志状态(损毁、权限受限等) 标志类型通过不同形状区分,标志的平面与高程精度则通过颜色表示。 本网络服务可使用户轻松将SCIMS平台的测量控制标志数据集成至符合开放地理空间联盟(OGC,Open Geospatial Consortium)标准的空间平台与应用程序中。 新南威尔士州测量标志网络服务所提供的数据可应用于各类工程与测量场景,包括但不限于: · 地籍测量规划 · 洪水研究与水文模拟 · 基础设施建设 · 施工现场点位校准 · 高程建模 · 测量基础设施保护 新南威尔士州测量标志网络服务为用户提供了一种替代途径,可无需登录SCIMS在线平台即可获取国家控制测量数据,并将其集成至自身的GIS软件中。 请注意,SCIMS在线平台是获取地籍测量所需国家控制测量数据的官方途径,因其具备法律溯源性。用户可通过空间门户访问SCIMS在线平台。 #### 首次发布日期 2019年7月1日 #### 数据时效性 3000年1月1日 #### 数据更新频率 每日 #### 内容来源 数据提供方文件 #### 文件类型 ESRI文件地理数据库(*.gdb) #### 署名 © 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)。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 基础空间数据框架(FSDF,Foundation Spatial Data Framework)下的NSW定位主题;基础空间数据框架(FSDF)下的NSW高程与深度主题 #### 精度说明 本数据集基于GDA94坐标系坐标展示测量标志的位置。官方GDA94坐标自2019年7月1日起未再更新。如需获取精准数据,请参考《NSW定位主题——测量标志GDA2020多坐标系("multiCRS")》或《NSW定位主题——测量标志GDA2020》。 如需更多信息,请通过空间服务客户中心(Spatial Services Customer Hub)联系我们。 #### 空间参考系(数据集) GDA94 #### 空间参考系(网络服务) 其他 #### WGS84等效基准 GDA94 #### 空间范围 全州范围 #### 内容溯源 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 非机密 #### 数据访问政策 开放 #### 数据质量 高。方法学与精度标准符合新南威尔士州测量总监发布的规范。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 #### 标准与规范 符合开放地理空间联盟(OGC)标准,可兼容主流GIS平台使用。可根据客户端需求选择缓存或非缓存服务。 #### 数据保管方 新南威尔士州客户服务厅空间服务部 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。 #### 数据整合方 新南威尔士州客户服务厅空间服务部 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 新南威尔士州客户服务厅空间服务部 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 方法学与精度标准符合新南威尔士州测量总监发布的规范。 数据字典
