NSW Positioning Theme - Survey Marks GDA2020

Content TitleNSW Positioning Theme Survey Mark GDA2020 multiCRSContent TypeMap Image LayerDescription

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). 
This service supports requests in multiple coordinate reference systems.
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:<ul><li>Mark type (Permanent Mark, State Survey Mark, etc.) </li><li>Mark number </li><li>Horizontal coordinates and their accuracy (class and order) </li><li>Heights and their accuracy (class and order) </li><li>Status of the mark (destroyed, restricted access, etc.) </li></ul>
 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: <ul><li>Cadastral survey planning </li><li>Flood studies and hydrographic modelling </li><li>Infrastructure development</li><li>Site calibration at construction sites </li><li>Elevation modelling </li><li>Preservation of survey infrastructure.</li></ul>
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.
<i><b>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.</b></i>
