NOAA Topobathy Lidar: DeSoto to Boca Grande, Florida, 2017

Data were acquired from October 10 to October 27, 2017, by the NOAA National Geodetic Survey using a Riegl VQ880G system. The dataset includes topobathy lidar point clouds in LAS 1.4 format, with classifications for ground, water surface, bathymetric bottom, and submerged objects. 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 bottom points.
• Analyzing submerged topography and object detection based on classifications for submerged objects and bathymetric bottom.
• Differentiating between water surface and land features based on the provided point classifications.
• Generating 3D coastal elevation models based on the topobathy lidar point cloud data.

Strengths

• Data collection uses a specific, named sensor system (Riegl VQ880G).
• Point cloud classifications are defined for key features like ground, water surface, and bathymetric bottom.
• Data acquisition occurred over a specific 18-day period in October 2017.

Limitations

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