Tertiary Sediment Cell Boundaries for Coastal Management

Coastal Information, Department of Transport provides boundaries for tertiary sediment cells, which are natural coastal management units defined by sediment exchange processes. The dataset includes areas of sediment sources, sinks, and transport pathways, represented as two-dimensional spatial features. It is licensed under CC-BY and was last updated in March 2026.

Use Cases

• Delineate natural coastal management units using the sediment cell boundary features for cross-jurisdictional planning.
• Analyze sediment transport pathways and connectivity between marine and terrestrial landforms within defined cell areas.
• Model sediment budgets by identifying sediment supply sources and loss sinks within the spatial cell framework.

Strengths

• Data is provided by the authoritative Department of Transport, ensuring institutional credibility.
• Spatial representation of two-dimensional cells captures both alongshore and cross-shore sediment processes.
• Released under a permissive CC-BY license, facilitating reuse and integration.

Limitations

• The dataset lacks metadata on row count, column count, and file size, hindering assessment of scale.
• Sample data is unavailable, preventing preview of attribute fields or spatial geometry before download.
• Specific temporal coverage and geographic extent for the boundary points are not stated.
