NSW Water Feature Corridor Cadastral Boundaries

Water Feature Corridor represents spatial extents of water features, including high water mark, low water mark, tidal influence limits, and bay closing lines. Spatial Services continuously updates the dataset with information sourced from stakeholders like Crown Lands and the Office of Environment and Heritage. Data is updated within 10 working days from when a plan is lodged.

Use Cases

• Define allowable land use by analyzing the spatial extents of water feature corridors.
• Manage disaster response planning using the high water mark and low water mark features for flood modeling.
• Support native title and heritage protection assessments by mapping the delineation between different water feature types.
• Improve infrastructure development planning by integrating bay closing lines and tidal influence limits into site analysis.
• Inform water accounting programs by utilizing the dataset's cadastral features representing water feature extents.

Strengths

• Data is updated within 10 working days from plan lodgement, ensuring recent cadastral changes are captured.
• Data quality is assured through specification compliance and data topology rules for maintenance and upgrade activities.
• Dataset includes specific cadastral features like high water mark, low water mark, and bay closing lines.

Limitations

• The dataset uses the GDA94 spatial reference, which cannot be easily consumed into GDA2020 environments, creating a technical barrier.
• The specific row count, column names, and total data size are unknown, limiting precise assessment of scale.
• Data is sourced from multiple government bodies, which may introduce inconsistencies in update timing or format.
