NOAA Topobathy Lidar DEM for Hurricane Michael Impact Zone, 2019-2020

2019 - 2020 NOAA NGS Topobathy Lidar DEM: Hurricane Michael is a topobathymetric digital elevation model covering approximately 2,120,060 acres of the Florida Panhandle. The data were collected by contractors including NV5 and Dewberry using a Leica Chiroptera 4X system between November 2019 and July 2020. It is provided in geoTIFF format at a 1-meter horizontal resolution.

Use Cases

• Modeling coastal inundation and storm surge based on high-resolution elevation and bathymetry data.
• Assessing hurricane-induced erosion and sediment transport based on integrated land and seafloor topography.
• Monitoring post-storm coastal recovery and habitat changes based on detailed elevation models.
• Supporting coastal resilience planning and infrastructure siting based on accurate topographic and bathymetric mapping.

Strengths

• Covers a large, contiguous area of approximately 2,120,060 acres.
• Provides integrated topographic and bathymetric data at a high 1-meter horizontal resolution.
• Data collection is attributed to specific contractors and a named sensor system (Leica Chiroptera 4X).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The primary file format listed is PDF, which may not contain the raw geospatial data directly.
• Row count is unknown, which may limit suitability assessment for certain analyses.
