2022 Florida Coastal Topobathy Lidar from Bayonet Point to Cedar Key

From October 18 to December 3, 2022, Dewberry collected topobathy lidar data using a CZMIL Super Nova system for the National Oceanic and Atmospheric Administration. The dataset covers approximately 1,373 square miles along Florida's Big Bend coast and contains 17,639 classified 500-meter tiles. The South Block subset comprises 9,585 of these tiles.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and bathymetric bottom points.
• Analyzing seafloor topography and nearshore features based on bathymetric bottom classifications.
• Generating digital elevation models for coastal zones based on classified ground and water surface points.
• Assessing coastal inundation risks based on the integrated topographic and bathymetric elevation data.

Strengths

• Data collection occurred over a defined period from 20221018 to 20221203.
• Covers a specific, large geographic area of approximately 1,373 square miles.
• Data is classified into specific categories like ground, water surface, and bathymetric bottom.

Limitations

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