2019 NOAA Topobathy Lidar for Tampa Bay, Florida

311 square miles of topobathymetric lidar data covering Tampa Bay, Florida, collected by Leading Edge Geomatics for NOAA. The data were acquired from November 22 to December 20, 2019, and are delivered in two blocks totaling 1,788 tiles. The point cloud data is in LAS 1.4 format with classifications for ground, water surface, bathymetric bottom, and other features.

Use Cases

• Modeling coastal erosion and sediment transport based on detailed elevation and bathymetry data.
• Creating high-resolution digital elevation models (DEMs) for flood risk assessment based on classified ground and water surface points.
• Analyzing seafloor topography and submerged object detection based on bathymetric bottom and submerged object classifications.
• Monitoring changes in coastal morphology and infrastructure based on temporal point classifications.

Strengths

• Covers a specific, significant coastal area of approximately 311 square miles.
• Data is classified into specific categories like ground, water surface, and bathymetric bottom, facilitating targeted analysis.
• Acquired over a focused one-month period (November-December 2019), providing a temporal snapshot.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description does not specify the point density or vertical accuracy, which are critical for many applications.
