Spatial Services Address Database (also known as GURAS- Geocoded Urban and Rural Addressing System) is the authoritative property addressing dataset for NSW. Geo-coded addressing is a theme of the NSW Foundation Spatial Data Framework (FSDF) which aims to ensure that single point of truth, authoritative, reliable and up-to-date spatial data is available to support NSW in decision-making, government, business and community use. Spatial Services is the designated custodian for FSDF geo-coded address data.
The database is currently 'Property' based, i.e. every property as defined by the Valuer General of NSW contains at least one authoritative address which is sourced from local councils. Properties may also contain extra addresses sourced from other various organisations e.g. Councils, Australia Post or site administrators.
Key elements include:
- Address Strings (aspatial information, generally house number, road name and type, and locality)
- Address Points
- Way Points (Access Points).
It is important to note that Address Points are generally system generated points and therefore do not always have a direct correlation to the dwelling location. In circumstances where there are multiple disparate lots for the one property, particularly in rural addresses, the system generated Address Points may not reside within the correct property polygon. Owners names are not part of the Address database, nor does it contain any personal information.
GURAS is continuously updated through automated batching processes of property and address information sourced from Valnet, spatially structured components sourced from the DCDB (legal boundaries) and DTDB (road names and extents), Australia Post, Councils, Geographical Names Board and Transport for NSW.
The Address database is widely used by Local and State Government agencies in NSW for purposes such as Address verification, emergency services, computer aided dispatch systems, postal and delivery services, and as a common identification of location. Spatial Services addresses are also contributed daily to the Geo-coded National Address File (G-NAF) environment maintained by PSMA Australia, used across government and industry to verify addresses, identify addresses on a map and link to statistical and business information.

Spatial Services is now providing spatial data as web services. The web services have been released under open access licenses as part of the NSW Government Open Data Policy to support new and innovative uses of NSW Government information.
The web services allow users to access the most up to date information without having to store and maintain it in their own systems or applications. The web services can be used in multiple ways e.g. direct use, mashups, mobile apps and spatial systems.
