2022 Florida Coastal Lidar DEM: Bayonet Point to Cedar Key

Florida's Big Bend coastal region from Bayonet Point to Cedar Key was surveyed using a CZMIL Super Nova system between October 18 and December 3, 2022. The dataset contains approximately 1,373 square miles of topobathy data, delivered as 118 5,000 m x 5,000 m DEM tiles. It was collected by Dewberry for the National Oceanic and Atmospheric Administration.

Use Cases

• Model coastal erosion and accretion based on classified ground and bathymetric bottom points.
• Analyze seafloor topography and water surface dynamics based on bathymetric and water surface classifications.
• Create high-resolution digital elevation models for flood risk assessment based on the 5,000 m tile structure.
• Filter and process lidar point clouds based on classifications for noise, ground, and water.

Strengths

• Data covers approximately 1,373 square miles of coastal area.
• Collection occurred over a defined period from 20221018 to 20221203.
• Point cloud data includes specific classifications for ground, water surface, and bathymetric bottom.
• Dataset is structured into 118 standardized 5,000 m x 5,000 m tiles.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific survey area of the Big Bend region.
