NSW Positioning Theme - Survey Mark GDA94

NSW Positioning Theme - Survey Mark GDA94Note: GDA94 coordinates for NSW survey marks are no longer maintained. This data has been superseded by NSW Positioning Theme Survey Mark GDA2020 multiCRS or NSW Positioning Theme - Survey Mark GDA2020.Please Note:WGS 84 service
aligned to GDA94
This dataset has spatial reference [WGS 84 ≈ GDA94] which may result in misalignments when
viewed in GDA2020 environments.  A similar service with a ‘multiCRS’
suffix is available which can support GDA2020, GDA94 and WGS 84 ≈ GDA2020
environments.In due course, and allowing time for user feedback and testing, it is intended
that the original service name will adopt the new multiCRS functionally.

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 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.
