Brief description

NSW Positioning Theme Survey Mark GDA2020

Please Note

WGS 84 = GDA2020 service

This dataset has a spatial reference of [WGS 84 = GDA2020] and can NOT be easily consumed into GDA94 environments. A similar service with a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS84 = GDA94 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.

Description

The 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 GDA2020 coordinates, heights and related information for NSW survey marks that form the official State control survey network (as reported in SCIMS), plotted in their GDA2020 locations (equivalent to WGS84@2020). This service controls the precision of numerical output in a manner that mirrors SCIMS Online.

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 development
  • Site 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. SCIMS online is accessible via the Spatial portal.
