Miami Coastal Digital Elevation Model at 10-Meter Resolution

NOAA's 1/3 arc-second (~10-meter) resolution digital elevation model integrates bathymetric and topographic data for the Miami, Florida coastal region. The DEM is referenced to the NAVD 88 vertical datum and WGS 84 horizontal datum to support tsunami hazard mitigation and coastal preparedness. It is compiled from multiple federal, state, and local sources including NOAA and the U.S. Geological Survey.

Use Cases

• Model coastal inundation and tsunami hazards using the integrated bathymetric-topographic elevation grid.
• Analyze coastal relief and shoreline changes with the 10-meter resolution elevation data.
• Support community planning and hazard mitigation for the East Coast, Florida region using the NAVD 88 referenced DEM.

Strengths

• High-resolution 1/3 arc-second (~10-meter) grid spacing for detailed coastal analysis.
• Integrated bathymetric and topographic data from authoritative sources like NOAA and USGS.
• Specifically compiled to support the National Tsunami Hazard Mitigation Program (NTHMP).

Limitations

• Spatial coverage is limited to select U.S. coastal regions, specifically the Miami area.
• The dataset's compilation from multiple sources may introduce inconsistencies in data quality or vintage.
• No information is provided on the temporal range or update frequency of the underlying source data.
