Topobathy Lidar Data for Southern Tampa Bay, Florida (2021)

A 2021 lidar point cloud dataset covering approximately 225 square miles along the shores of Tampa Bay, Florida. The data were collected by Dewberry using a CZMIL Nova system between January 26 and February 27, 2021, and include 3,180 tiles. Points are classified into categories such as ground, water surface, bathymetric bottom, and submerged objects.

Use Cases

• Coastal erosion modeling based on classified ground and bathymetric points.
• Seafloor and submerged object mapping based on bathymetric bottom and submerged object classifications.
• Shoreline delineation and change detection based on water surface and ground point data.
• Habitat mapping for coastal ecosystems based on the detailed topographic and bathymetric relief.

Strengths

• Data covers approximately 225 square miles, providing substantial spatial coverage.
• Includes 3,180 individual 500m x 500m tiles for granular analysis.
• Points are classified into 10 distinct categories (e.g., ground, water surface, bathymetric bottom), enabling feature-specific analysis.

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.
• Data may reflect geographic bias inherent to the specific Tampa Bay collection area.
