2017 Topobathy Lidar Digital Elevation Model for Dog Island, Florida

A lidar point cloud dataset 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. It includes 616 tiles of 500 m x 500 m data classified for topographic and bathymetric features.

Use Cases

• Modeling coastal erosion and sediment transport based on combined topographic and bathymetric elevation data.
• Creating high-resolution digital elevation models (DEMs) for flood risk assessment based on the classified ground and water surface points.
• Analyzing seafloor topography for habitat mapping based on the bathymetric bottom classifications.
• Calibrating hydrodynamic models using the water column and surface data points.

Strengths

• Data collection uses a specific, high-grade sensor (Riegl VQ880G).
• Covers a defined area of approximately 35 square miles with 616 individual tiles.
• Includes classified points for both topographic and bathymetric features (e.g., ground, water surface, bathymetric bottom).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a specific three-day period in 2017, which may limit temporal analysis.
