<i><b>Note: GDA94 coordinates for NSW survey marks are no longer maintained. This data has been superseded by NSW Positioning Theme Survey Mark GDA2020 multiCRS or NSW Positioning Theme - Survey Mark GDA2020</b></i>

<i>A new series of ‘multiCRS’ web services have been published to support GDA2020.  These new ‘multiCRS’ services:</i><i></i>

·         <i>have a spatial reference of GDA2020</i><i></i>

·         <i>support alignment with GDA2020, GDA94 or [WGS 84-aligned-to-GDA2020] GIS environments,using built-in server-side transformations:</i>

o    <i>GDA94 &lt; NTv2-CPD &gt; GDA2020</i><i></i>

o    <i>GDA94 &lt; NTv2-CPD &gt; WGS 84 aligned to GDA2020</i><i></i>

o    <i>GDA2020 &lt; NULL &gt; WGS 84 aligned to GDA2020</i>



<i><b>     Note</b>: ESRI software will automatically align by transforming from the sourceSpatialReference (GDA94).</i><i>               Other software may need to set client-side transformations from the SpatialReference (GDA2020).</i>


<strong><i>     Note: </i></strong><i>Client-side transformation(s) can be used to over-ride these default transformations.</i>

<i></i>
<i>The original [</i><i>WGS 84-aligned-to-GDA2020</i><i>] is still available, without the ‘multiCRS’ suffix. In due course, and allowing time for user feedback and testing, it is intended that the original service name will adopt this new 'multiCRS' functionality.</i>

Content TitleNSW Positioning Theme - Survey Mark GDA94 multiCRSContent TypeHosted Feature LayerDescription

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:<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.
