Coastal Topobathymetric Lidar for Miami, Florida (2017)

Lidar point cloud data covering approximately 53,381 acres along the Atlantic Coast of Miami, Florida. The data were collected by NOAA's National Geodetic Survey using a Riegl VQ880G system between February 24 and March 10, 2017. Quantum Spatial Inc processed the data, which includes classifications for ground, bathymetric bottom, and submerged features, delivered in 500m x 500m LAS tiles.

Use Cases

• Model coastal erosion and sediment transport based on classified ground and submerged topography points.
• Create high-resolution digital elevation models (DEMs) for flood risk assessment based on the topobathymetric data.
• Analyze changes in seafloor morphology and submerged features based on the bathymetric classification.
• Support coastal zone management and habitat mapping based on the integrated land and underwater elevation data.

Strengths

• Data covers a specific, large area of approximately 53,381 acres.
• Includes specialized classifications for bathymetric bottom (26) and submerged features (29).
• Collected over a defined period (20170224 - 20170310) in five missions, suggesting controlled acquisition.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific Miami Intracoastal project area.
