NSW Positioning Theme - NSW Survey Marks


Please Note

WGS 84 = GDA94 service

This dataset has a spatial reference of [WGS 84 = GDA94] and can NOT be easily consumed into GDA2020 environments. A similar service with a \u2018multiCRS\u2019 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.

Content TitleNSW Positioning Theme - NSW Survey Marks
Content TypeHosted Feature Layer
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.

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.)

\u00a0The 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 Collaboration Portal.

AccuracyThis dataset was captured by utilising the best available source at a variety of scales and accuracies, ranging from 1:500 to 1:250 000 according to the National Mapping Council of Australia, Standards of Map Accuracy (1975). 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.
