Big Bend, Florida Topobathy Lidar Data from 2022 NOAA Survey

Big Bend Wildlife Management Area, Florida, coastal data covering approximately 1,373 square miles. The National Oceanic and Atmospheric Administration collected these topobathy lidar point clouds using a CZMIL Super Nova system from October 27 to November 29, 2022. The dataset includes 17,482 tiles, with the North Block subset containing 8,054 individual 500-meter by 500-meter tiles.

Use Cases

• Model coastal erosion and sediment transport based on classified ground and bathymetric bottom points.
• Map submerged objects like wrecks or rocks based on the 'submerged object' classification category.
• Generate digital elevation models (DEMs) for coastal zones using classified ground and water surface points.
• Analyze the transition from land to seafloor using the combined topographic and bathymetric (topobathy) data.

Strengths

• Data covers a large, defined coastal area of approximately 1,373 square miles.
• Point clouds are classified into specific categories including ground, water surface, and bathymetric bottom.
• Acquisition dates (20221027-20221129) and the collection system (CZMIL Super Nova) are explicitly documented.

Limitations

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