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

2019 - 2020 NOAA NGS Topobathy Lidar: Hurricane Michael data were collected by contractors NV5 and Dewberry for the National Oceanic and Atmospheric Administration. The dataset covers approximately 2,120,060 acres in the Florida Panhandle, extending south to New Port Richey, and was collected between November 2019 and July 2020. It includes topobathymetric point cloud data in LAS format, with intensity values, return information, time, and scan angle, compiled into 44,926 tiles.

Use Cases

• Modeling coastal erosion and sediment transport based on integrated topographic and bathymetric elevation data.
• Assessing hurricane damage to shorelines and nearshore environments based on high-resolution lidar point clouds.
• Creating digital elevation models (DEMs) for flood risk analysis based on the detailed terrain and seafloor data.
• Analyzing lidar return characteristics for land cover classification based on intensity and number of returns.

Strengths

• Covers a large, defined area of approximately 2,120,060 acres.
• Provides integrated topobathymetric data, capturing both land and shallow water elevations.
• Data is organized into a manageable 44,926 tiles of 500 m x 500 m.
• Includes specific sensor information (Leica Chiroptera 4X system) and collection timeframe.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale processing.
