2019 NOAA Topobathy Lidar DEM for Tampa Bay, Florida

Topobathymetric lidar data covering approximately 311 square miles of the Tampa Bay inlet, including Old Tampa Bay and Hillsborough Bay. The data were collected by Leading Edge Geomatics using a RIEGL VQ880-G system between November 22 and December 20, 2019. The National Oceanic and Atmospheric Administration (NOAA) National Geodetic Survey (NGS) is the authoritative source.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and bathymetric bottom points.
• Analyzing seafloor topography and submerged objects based on the bathymetric classification scheme.
• Creating digital elevation models (DEMs) for flood risk assessment based on ground and water surface point classifications.
• Studying coastal habitat changes by comparing classified ground, water, and temporal points.

Strengths

• Data covers a defined area of approximately 311 square miles within Tampa Bay.
• Point cloud data is classified into specific categories like ground, water surface, and bathymetric bottom.
• Collection dates are precisely specified from November 22 to December 20, 2019.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The primary file format listed is PDF, which may not contain the raw point cloud data directly.
• Data may reflect geographic bias inherent to the specific Tampa Bay survey area.
