New South Wales Inland Water Body Points with Perennial Status

A geospatial point dataset representing standard bodies of inland water in New South Wales, Australia, where flow is minor. The data distinguishes between natural and man-made water bodies and indicates whether each point is perennial, non-perennial, or mainly dry. It is provided by Spatial Services (DCS) and is scheduled for retirement, with users directed to transition to a newer GDA2020 service.

Use Cases

• Classify water body type (natural or man-made) for environmental planning and cadastral parcel analysis.
• Analyze perennial status (perennial, non-perennial, mainly dry) of water points for water security and climate change studies.
• Map the spatial distribution of minor inland water bodies for emergency management response and hazard mitigation planning.
• Integrate point features as the NSW component of the Australian Hydrological Geospatial Fabric for national water resource information systems.

Strengths

• Dataset is part of a state-level digital Topographic database, indicating a structured collection process.
• Provides specific attribute classifications for water body type and perennial status.

Limitations

• The spatial reference (WGS 84 ≈ GDA94) may cause misalignments in modern GDA2020 coordinate systems.
• The service is explicitly marked as retiring, indicating potential future unavailability and requiring user migration.
• Specific quantitative metrics like total row count or geographic extent are not provided in the available metadata.
