Overland Flow Reliability Notes for Moreton Bay Flood Model

City of Moreton Bay's Data Hub provides a spatial dataset describing the expected reliability of flood data. It defines polygons indicating areas where the council assesses the flood model data has limited reliability or is subject to review. The dataset was last updated in March 2026.

Use Cases

• Map polygons of limited data reliability to prioritize field validation efforts for flood models.
• Integrate reliability notes polygons with flood hazard layers to qualify risk assessment confidence.
• Analyze spatial patterns of lower reliability areas to guide future flood model refinement projects.

Strengths

• Spatially explicit polygons provide direct geographic context for data reliability notes.
• Managed and updated by the authoritative local government body, City of Moreton Bay.
• Offered in multiple GIS formats including GeoJSON and KML for interoperability.

Limitations

• Dataset size, row count, and specific attribute columns are not documented.
• Reliability assessments are subjective opinions of the council, not quantified metrics.
• Focus is limited to the jurisdictional area of the City of Moreton Bay.
