Topobathy Lidar Elevation Model for Boca Grande, Florida, 2016

May 11-14, 2016 data collection by NOAA using a Riegl VQ880G sensor. The dataset covers approximately 85 square miles along the shores of Boca Grande, Florida, and contains 1,053 individual 500 m x 500 m lidar tiles. Data is provided in LAS 1.2 format with classifications for ground, water surface, bathymetric bottom, and other features.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and bathymetric bottom data.
• Analyzing seafloor topography and coastal terrain integration from the topobathy lidar data.
• Creating high-resolution digital elevation models (DEMs) for flood risk assessment based on the classified elevation points.
• Studying water column and surface features for hydrodynamic modeling based on the relevant point classifications.

Strengths

• Data collection dates are precisely specified as May 11-14, 2016.
• Spatial coverage is quantified as approximately 85 square miles.
• Dataset structure is defined as 1,053 individual 500 m x 500 m tiles.
• Point classification scheme is detailed, including ground, water surface, and bathymetric categories.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data format is LAS, which may require specialized software (e.g., LAStools, PDAL) for processing.
• Freshness should be verified; the last metadata update is from 2026-03-13.
