Miami Coastal Digital Elevation Model at 1/3 Arc-Second Resolution

NOAA's National Geophysical Data Center built a high-resolution integrated bathymetric-topographic digital elevation model for the Miami coastal region. The DEM has a grid spacing of 1/3 arc-second, approximately 10 meters, and is referenced to the NAVD 88 vertical datum and WGS 84 horizontal datum. It supports state-level coastal hazard mitigation efforts under the National Tsunami Hazard Mitigation Program.

Use Cases

• Model tsunami inundation and coastal flooding using the integrated bathymetric-topographic elevation data.
• Analyze coastal processes and shoreline change with the 10-meter resolution gridded elevation data.
• Support marine navigation and habitat mapping with the detailed bathymetry and seafloor topography data.

Strengths

• High-resolution grid spacing of 1/3 arc-second (~10 meters).
• Integrated bathymetric and topographic data from multiple authoritative sources including NOAA and USGS.
• Data is referenced to standard vertical (NAVD 88) and horizontal (WGS 84) datums for consistency.

Limitations

• Spatial coverage is limited to the select Miami coastal region and does not cover other areas.
• The specific data compilation date and temporal coverage are not provided in the input.
