Our services


Spatial Services implements and monitors standards for the survey industry in NSW. It does this by review and update of the Surveying and Spatial Information Regulation and Surveyor-General’s Directions and also conducts examination surveys in known areas of unreliable survey data and audit surveys of recently lodged plans. The Surveyor-General is also a verifying authority for length in NSW. 

An essential tool for surveyors is the State Control Survey Network, which is available to users online. A comprehensive network of permanent survey marks with known latitude, longitude and height, the State Control Survey Network provides certainty and confidence when determining property boundaries and during the construction of public infrastructure. In order to manage the State Control Survey Network, an approved datum for all positions (currently GDA94) and heights (currently AHD71) is required.

Spatial Services owns and operates CORSnet-NSW, a network of permanent satellite-tracking stations situated throughout the State that enables surveyors and users to utilise modern surveying technologies to accurately determine position. CORSnet-NSW enables the guidance of machinery used in construction, mining and agriculture, achieving greater efficiencies. CORSnet-NSW supports scientific research and industrial innovation across many sectors

Mapping and spatial information

Spatial Services manages the wealth of land data it collects into a comprehensive and authoritative range of online and hard copy mapping products and services. These products and services help support a vast range of community, business and government activity – everything from tourism and land management, to electoral boundaries and bushfire control.

As the primary source of land information for NSW, Spatial Services is responsible for maintaining a digital cadastral map of the State, which shows legal and other approved boundaries applying to land, as well as a digital topographic map, which shows its physical and surface features.

It also provides aerial photography, satellite imagery, accurate surface elevation and surface modelling, addressing information, touring maps and a unique customised mapping service that tailors spatial information to meet specific needs.
