Coastal Topobathy Lidar for Fort Lauderdale to Highland Beach, Florida

A 2018 airborne lidar survey collected by NOAA's National Geodetic Survey using a Riegl VQ880G system. The data includes both topographic and bathymetric points classified as ground, noise, bathymetric point, and submerged object according to ASPRS standards. It may also contain lidar intensity values and encoded RGB image values.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and bathymetric points.
• Mapping submerged objects and seafloor topography for navigation safety based on the bathymetric point classification.
• Analyzing coastal elevation changes by integrating topographic and bathymetric lidar data.
• Creating 3D visualizations of the coastal zone using the point-cloud data and potential RGB values.

Strengths

• Data collected by a national authoritative agency (NOAA National Geodetic Survey).
• Points are classified to ASPRS standards, including specific classes for bathymetry (26) and submerged objects (29).
• Data format is LAS 1.4, a standard for lidar point cloud interchange.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
