Coastal Topobathy Lidar for Chatham Bay to Monomoy Point, Massachusetts (2022)

Massachusetts coastal data from Chatham Bay to Monomoy Point collected by the NOAA National Geodetic Survey using a Leica Chiroptera 4X airborne lidar system. The point cloud data, acquired between June 5 and July 23, 2022, includes topographic and bathymetric returns classified according to ASPRS standards, with categories for ground, water surface, submerged features, and vegetation. The data may also include lidar intensity values.

Use Cases

• Modeling coastal erosion and sediment transport based on classified ground and submerged feature points.
• Mapping submerged aquatic vegetation habitats based on the specific classification for this feature.
• Creating integrated digital elevation models (DEMs) for coastal zones based on combined topographic and bathymetric point data.
• Analyzing nearshore water surface dynamics based on the separate classifications for topographic and bathymetric water surface returns.

Strengths

• Data collection uses a specific, named sensor system (Leica Chiroptera 4X).
• Point classification follows the standardized ASPRS scheme, including distinct codes for bathymetry and submerged features.
• Acquisition period is precisely defined from 20220605 to 20220723.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data volume are unknown, which may limit suitability assessment.
