2022 NOAA Topobathy Lidar for Maryland Coast

Lidar data classified into nine distinct categories, including ground, water surface, and submerged objects, in accordance with ASPRS standards. The National Oceanic and Atmospheric Administration collected this data via airplane using a Leica Hawkeye4X system. Acquisition occurred from November 3, 2022, through February 5, 2023, covering the area from Bethany Beach to Chincoteague, Maryland.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and bathymetric points.
• Mapping submerged objects and underwater topography based on the submerged object and bathymetric point classifications.
• Analyzing coastal terrain and water surface dynamics based on the distinct topo water surface and bathymetric water surface classes.

Strengths

• Data is classified into nine specific categories (e.g., ground, water surface, submerged object) using ASPRS standards.
• Collection period is precisely defined from November 3, 2022, to February 5, 2023.
• Data was acquired using a specified Leica Hawkeye4X system from an airplane.

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.
