NSW Positioning Theme Survey Mark GDA94

Export Data Access APINSW Positioning Theme Survey Mark GDA94Note: GDA94 coordinates for NSW survey marks are no longer maintained. This data has been superseded by NSW Positioning Theme Survey Mark GDA2020 multiCRS or NSW Positioning Theme - Survey Mark GDA2020.Please Note:WGS 84 service\naligned to GDA94\nThis dataset has spatial reference [WGS 84 ≈ GDA94] which may result in misalignments when\nviewed in GDA2020 environments.  A similar service with a ‘multiCRS’\nsuffix is available which can support GDA2020, GDA94 and WGS 84 ≈ GDA2020\nenvironments.In due course, and allowing time for user feedback and testing, it is intended\nthat the original service name will adopt the new multiCRS functionally.\n\nPlease note that\nSCIMS Online is the official option for obtaining state control survey data for\ncadastral surveys as it offers legal traceability. SCIMS online is accessible\nvia the Spatial portal.Metadata Portal Metadata InformationContent TitleNSW Positioning Theme Survey Mark GDA94Content TypeHosted Feature LayerDescriptionThe NSW Survey Marks web service is a dynamic map of permanent survey marks that constitute the state control survey. The positioning data under the NSW Foundation Spatial Data Framework (FSDF) is fed to the web service by the Survey Control Information Management System (SCIMS), the database that contains the single source of truth for all marks within the state control survey network.This 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 infrastructureThe 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：新南威尔士州定位主题 测量标志 GDA94（Geocentric Datum of Australia 1994）
注：新南威尔士州测量标志的GDA94坐标现已不再维护。本数据集已被《新南威尔士州定位主题 测量标志 GDA2020 multiCRS》或《新南威尔士州定位主题——测量标志 GDA2020》替代。
请注意：WGS 84（World Geodetic System 1984）服务与GDA94对齐。
本数据集的空间参考为[WGS 84 ≈ GDA94]，在GDA2020环境中查看时可能出现坐标偏移。另有一款后缀为“multiCRS”的同类服务，可支持GDA2020、GDA94以及WGS 84 ≈ GDA2020环境。
在预留用户反馈与测试周期后，本服务原名称将逐步启用multiCRS功能。
请注意：如需获取用于地籍调查的州级控制测量数据，测量控制信息管理系统（Survey Control Information Management System，简称SCIMS）在线平台为官方渠道，其具备法律溯源性。可通过空间门户访问SCIMS Online。

内容标题：新南威尔士州定位主题 测量标志 GDA94
内容类型：托管要素图层
描述：新南威尔士州测量标志网络服务为构成州级控制测量体系的永久测量标志提供动态地图服务。新南威尔士州基础空间数据框架（Foundation Spatial Data Framework，简称FSDF）下的定位数据由SCIMS推送至本网络服务，该系统存储了州级控制测量网络内所有测量标志的权威单一数据源。
本服务可为构成官方州级控制测量网络的新南威尔士州测量标志提供GDA94坐标、高程及相关信息（数据来自SCIMS）。本服务的数值输出精度规则与通过空间服务门户访问的SCIMS Online保持一致。
本网络服务可提供各测量标志的丰富数据，包括：
- 标志类型（永久标志、州级测量标志等）
- 标志编号
- 平面坐标及其精度（等级与阶数）
- 高程及其精度（等级与阶数）
- 标志状态（已损毁、限制进入等）
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体现。
本网络服务可使用户轻松将SCIMS中的测量控制标志数据集成至兼容开放地理空间联盟（Open Geospatial Consortium，简称OGC）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提供的数据可应用于多种工程与测量场景，包括但不限于：
- 地籍调查规划
- 洪水研究与水文建模
- 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另一种获取州级控制测量数据的渠道，用户可将数据直接集成至GIS软件中，无需登录SCIMS Online。
请注意：如需获取用于地籍调查的州级控制测量数据，SCIMS Online为官方渠道，其具备法律溯源性。可通过空间门户访问SCIMS Online。
