NEW

We have released a new GDA2020 version of our\u00a0Foundational Spatial Data Framework (FSDF) datasets\u00a0which replaces the current GDA94 version. This updated service aligns our spatial data with the national standard, improving accuracy, consistency, and compatibility with modern positioning technologies.

\u00a0

The previous service will remain available during the transition period as GDA94 services are retired, but users are encouraged to move to the new GDA2020 service as soon as practical.

Content TitleNamed Watercourse -\u00a0NSW Water Theme - GDA2020 Service
Content TypeHosted Feature Layer
DescriptionNSW Named Watercourse defines the centreline of a named water course as a single feature. It is an aggregation of Hydro Line parts.

Water security is one of Australia\u2019s major challenges.

Key users of the hydrology data are NSW State and Local Government agencies as well as Federal Government agencies. These bodies use this data to better manage State and Local Government assets.

This hydrology data provides the NSW component of the Australian Hydrological Geospatial Fabric which is a critical input to the Australian Water Resources Information System.

More widespread use of the hydrology data is also found in emergency management response and recovery efforts, hazard mitigation or disaster risk reduction, climate change, natural resource assessment, environmental planning and monitoring, insurance, mining and agriculture.

Spatial Services continuously updates this theme with information sourced from relevant stakeholders and custodians; by data verification from other internal and external databases; research and through Spatial Services\u2019 regular cycle of updating from aerial imagery and elevation data.

Data Theme, Classification or Relationship to other DatasetsNSW Water Theme\u00a0of the Foundation Spatial Data Framework (FSDF)
AccuracyThis\n dataset was captured by utilising the best available source at a \nvariety of scales and accuracies, ranging from 1:500 to 1:250 000 \naccording to the National Mapping Council of Australia, Standards of Map\n Accuracy (1975). Therefore, the position of the feature instance will \nbe within 0.5mm at map scale for 90% of the well-defined points. That \nis, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = \n25m and 1:100000 = 50m. A program to upgrade the spatial location and \naccuracy of data is ongoing.
