Survey information

Spatial Services – Department of Finance, Services and Innovation is responsible for maintaining the official State Control Survey Network, are liable and accurate spatial referencing system that underpins surveying, land information and mapping systems in NSW.

Spatial Services' role is to manage and improve the database that is the core of this network, while public and private sector surveyors (including our own surveyors) contribute to the currency of the system by recording and placing new permanent survey marks that extend the network on the ground.

The State Control Survey provides certainty and confidence when surveying the location of land and property for asset management, establishing property boundaries and constructing public infrastructure.

An essential tool for surveyors, State Control Survey data is available to registered users in the Spatial Services portal and through SCIMS Online.

Control Surveys and SCIMS

Surveyor General’s Direction No. 12 is a guide as to what is required before coordinates and heights will be placed on public record in the Survey Control Information Management System (SCIMS). Issues covered include marking, positioning technologies, survey practice, observation processing, least squares adjustment and reporting.

All submissions to update SCIMS with control survey data are required to include a Survey Report (DOC 61.0 KB) and Locality Sketch Plans for all marks placed. An example of a good Survey Report is provided in the Sample Survey Report (PDF 319.1 KB).

To assist with submission of GNSS (GPS) observations, a generic logsheet is available to download in PDF (PDF 14.7 KB) or Excel (XLS 28.5 KB) formats - with a worked example (PDF 412.5 KB).
