NSW’s authoritative, reliable, high accuracy spatial referencing system and it provides a common reference for all geospatial data. Services are used by specialists and non-specialists alike, for a growing number of applications (e.g. surveying, construction, mining, precision agriculture, asset capture, tracking, navigation, emergency response, law enforcement, insurance, security, climate/weather forecast and recreation). In order to maximise the benefits of positioning and the enabling infrastructure, and to provide assurance to users of the fitness for purpose of the position outputs, guiding principles are required to enable the consistent and reliable determination and use of position information. CORSnet-NSW Services are used internally by Surveyors to maintain and improve the NSW survey control network and by Aerial operations to determine precise trajectories of the airborne sensors of imagery and LiDAR missions.
