NSW Water Feature Corridor Cadastral Data in GDA2020

Water Feature Corridor data represents spatial extents of water features within the NSW Land Parcel and Property Theme. The dataset contains high water mark, low water mark, the limit of tidal influence and bay closing lines. Spatial Services continuously updates the data, sourced from stakeholders like Crown Lands and the Office of Environment and Heritage, and it is up to date to within 10 working days from plan lodgement.

Use Cases

• Define allowable land use based on water feature boundaries.
• Manage native title and nature conservation based on cadastral water feature extents.
• Improve infrastructure and property development planning based on spatial water corridor data.
• Inform water accounting programs based on high and low water mark delineations.

Strengths

• Data is updated to within 10 working days from plan lodgement.
• Aligns with the national GDA2020 standard, improving accuracy and compatibility.
• Data quality is assured through specification compliance and topology rules.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
