NOAA Topobathy Lidar for Florida Coast from Shell Key to Honeymoon Island

Lidar point cloud data collected by NOAA's National Geodetic Survey using a Riegl VQ880G system. The data includes classifications for ground, water surface, submerged objects, and aquatic vegetation 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 combined topographic and bathymetric elevation data.
• Classifying submerged aquatic vegetation habitats based on the SAV (64) point classification.
• Analyzing coastal land-water interface changes based on the toppbathy water surface (41) classification.
• Detecting underwater structures or debris based on the submerged object (43) classification.

Strengths

• Data collected by NOAA's National Geodetic Survey, a federal authoritative source.
• Points are classified according to ASPRS standards, including specific codes for bathymetry and submerged features.
• Data may contain both lidar intensity and encoded RGB values, providing multiple data layers.

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 Florida coastline surveyed.
