NSW Positioning Theme - NSW Survey Marks

NSW Positioning Theme - NSW Survey MarksPlease 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 Positioning Theme - NSW Survey MarksContent 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. 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.
