2017 NOAA Topobathy Lidar for Dog Island, Florida, 35 Square Miles

616 lidar tiles covering approximately 35 square miles along the shores of Dog Island, Florida. The data were collected by the National Oceanic and Atmospheric Administration using a Riegl VQ880G sensor from April 14 to 16, 2017. The point cloud data is in LAS 1.2 format and includes classifications for ground, water surface, bathymetric bottom, and water column.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and topographic noise points.
• Analyzing nearshore bathymetry for navigation and habitat mapping based on bathymetric bottom and water column classifications.
• Creating digital elevation models (DEMs) integrating land and seafloor topography based on topobathy point cloud data.
• Studying water surface dynamics and wave action based on the water surface classification layer.

Strengths

• Data covers a defined area of approximately 35 square miles.
• Point cloud includes specific classifications for ground, water surface, bathymetric bottom, and water column.
• Collection dates and sensor type (Riegl VQ880G) are explicitly documented.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
