Conducting a Cadastral Survey (For Registered Surveyors)

Find out what you need to do to conduct a cadastral survey as a Registered Surveyor

Last updated 1 August 2025

Depending on the request, the Registered Surveyor could make various types of cadastral survey submissions to SLA for processing. We are now in a paper-less environment whereby submissions made by the Registered Surveyor are in real-time and digital 100% electronic. 

The completion of a property boundary survey happens when the Chief Surveyor approves the survey plan submitted and certified by the Registered Surveyor. 

SLA stores and makes available approved survey maps and plans for the public to purchase via INLIS. The current types of survey plans can be found here.

Registered surveyors portal

The RS-Portal (opens in new tab) is a platform for Registered Surveyors (RS) to pre-validate and submit cadastral survey jobs to Chief Surveyor for approval. The web portal serves as a single window for services between SLA and the RS with the aim of increasing productivity and enhancing the ease of submission in a secured environment and digital. By allowing the RSs to submit in digital format - LandXML, the RS Portal has changed the fundamental how the cadastral data is processed, managed and exchanged across different platforms to meet challenges in the digital world.
