2022 NOAA Topobathy Lidar for Washington Island, Wisconsin

Washington Island, Wisconsin, and the shores of Green Bay are covered by approximately 219 square miles of topobathy lidar data. The National Oceanic and Atmospheric Administration collected this data using a CZMIL Super Nova system between July 19 and August 16, 2022. It consists of 2,630 LAS tiles and includes classified points for ground, water surface, and bathymetric bottom.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and bathymetric bottom points.
• Creating high-resolution digital elevation models for flood risk assessment based on the 1-meter grid DEMs mentioned.
• Mapping nearshore habitats and submerged objects based on the classified point categories for wrecks and rocks.
• Analyzing water surface dynamics based on the classified water surface and derived water surface points.

Strengths

• Data covers approximately 219 square miles, providing substantial spatial coverage.
• Includes 2,630 individual 500m x 500m tiles, which suggests manageable file sizes for processing.
• Point cloud is classified into specific categories like ground, water surface, and bathymetric bottom.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale processing.
