NSW Survey Mark

NSW Survey MarkPlease NoteWGS 84 = GDA94 serviceThis dataset has a spatial reference of [WGS 84 = GDA94] and can NOT be easily consumed into GDA2020 environments. A similar service with a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS84 = GDA2020 environments. In due course, and allowing time for user feedback and testing, it is intended that these original services will adopt the 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 Water Theme multiCRSContent 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.The web service provides a wealth of data on each mark, including:Mark type (Permanent Mark, State Survey Mark, etc.)Mark numberHorizontal 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 planningFlood studies and hydrographic modellingInfrastructure developmentSite calibration at construction sitesElevation modellingPreservation 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.

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.

新南威尔士州测量标记（WGS 84 = GDA94）服务
## 重要说明
请注意：本数据集的空间参考为【WGS 84 = GDA94】，无法直接适配GDA2020环境。另有带“multiCRS”后缀的同类服务，可支持GDA2020、GDA94及WGS84 = GDA2020环境。待收集用户反馈并完成测试后，本原始服务将逐步升级以支持多空间参考系统（multiCRS）功能。

请注意：用于地籍测量的州级控制测量数据，官方获取渠道为测量控制信息管理系统在线平台（Survey Control Information Management System Online，简称SCIMS Online），因其具备法律溯源性。用户可通过空间门户（Spatial portal）访问SCIMS Online。

### 服务描述
新南威尔士州测量标记网络服务是展示构成州级控制测量体系的永久测量标记的动态地图。新南威尔士州基础空间数据框架（Foundation Spatial Data Framework，FSDF）下的定位数据由测量控制信息管理系统（Survey Control Information Management System，SCIMS）推送至本网络服务，该数据库存储了州级控制测量网络内所有测量标记的权威单一数据源。

本网络服务可提供各测量标记的丰富数据，包括：
- 标记类型（永久标记、州级测量标记等）
- 标记编号
- 水平坐标及其精度（等级与阶数）
- 高程及其精度（等级与阶数）
- 标记状态（已损毁、限制进入等）

标记类型通过不同形状予以区分，标记的垂直与水平精度则通过颜色进行标识。

本网络服务支持用户轻松将SCIMS中的测量控制标记数据集成至符合开放地理空间联盟（Open Geospatial Consortium，OGC）标准的空间平台与应用中。

本服务提供的新南威尔士州测量标记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
- 洪水研究与水文建模
- 基础设施开发
- 施工现场点位校准
- 高程建模
- 测量基础设施保护

相较于需登录SCIMS Online平台的方式，本网络服务为用户提供了更便捷的途径，可将州级控制测量数据直接集成至GIS软件中。

请注意：用于地籍测量的州级控制测量数据，官方获取渠道仍为SCIMS Online，因其具备法律溯源性。用户可通过空间协作门户（Spatial Collaboration Portal）访问SCIMS Online。
