Storm Tide Flood Data Reliability Notes for Moreton Bay

City of Moreton Bay's Data Hub provides a polygon dataset describing areas with limited reliability in 5% Annual Exceedance Probability storm tide flood modeling. The dataset indicates specific locations and reasons for lower data reliability or areas subject to review. It was last updated in March 2026 by moretonbaygis.

Use Cases

• Identify spatial polygons where flood model data has limited reliability for risk assessment refinement.
• Analyze the stated reasons for limited data reliability across different geographic areas within the council region.
• Integrate reliability notes polygons with other flood hazard layers to qualify confidence in storm tide inundation extents.

Strengths

• Data is explicitly focused on qualifying model reliability, a critical metadata layer for hazard analysis.
• Published by a municipal authority (City of Moreton Bay) for a defined geographic area.
• Maintained with a recent update timestamp of March 2026.

Limitations

• The dataset contains qualitative notes on reliability rather than quantitative flood values.
• Spatial coverage is limited to the City of Moreton Bay council area.
• Underlying data volume (row/polygon count) and specific attribute columns are not documented.
