Limited Reliability Flood Model Areas for Moreton Bay

Moreton Bay GIS provides a polygon dataset describing areas of known lower reliability or under review for 0.1% Annual Exceedance Probability flood models. The dataset stores spatial definitions and reasons for limited data reliability. It is maintained by the City of Moreton Bay's Data Hub.

Use Cases

• Identify model areas with lower reliability using polygon spatial definitions for risk assessment
• Analyze reasons for limited flood data reliability to prioritize model review or field validation
• Integrate reliability notes polygons with other flood layers to qualify hazard interpretations

Strengths

• Data is updated regularly, with a last update timestamp of March 2026
• Spatial data is provided in multiple interoperable formats including GeoJSON and KML
• Dataset originates from the authoritative local government GIS unit for Moreton Bay

Limitations

• Dataset scope is limited to areas of known lower reliability, not a complete flood hazard assessment
• No quantitative row or feature count is provided to assess dataset scale
• Reliability assessments are based on Council opinion, which may be subjective
