2022 Topobathy Lidar DEM of Indian River Lagoon, Florida

615 square miles of topobathy lidar data covering the shores of Indian River Lagoon, Florida, collected by Dewberry for NOAA between February and June 2022. The dataset includes 136 tiles of 5km x 5km Digital Elevation Models with points classified as ground, water surface, submerged vegetation, and bathymetric bottom. Data are provided in LAS 1.4 format with classifications for terrain, water, and submerged features.

Use Cases

• Modeling coastal erosion and inundation based on detailed terrain and bathymetric elevation data.
• Mapping submerged aquatic vegetation habitats based on the classified point categories.
• Analyzing seafloor topography and identifying submerged objects like wrecks or rocks.
• Creating integrated land-water elevation models for hydrodynamic simulations.

Strengths

• Covers approximately 615 square miles, providing extensive spatial coverage for the lagoon area.
• Contains 136 standardized 5km x 5km DEM tiles for consistent processing.
• Includes multiple classified point types (e.g., ground, water surface, submerged vegetation) enabling feature-specific analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the last metadata update is from 2026.
