2022 NOAA Topobathy Lidar Point Cloud for Chesapeake Bay, VA

NOAA National Geodetic Survey collected topobathy lidar data for the Chesapeake Bay, Virginia area from November 3, 2022 through March 5, 2023. The data are in LAS 1.4 format and include points classified as ground, water surface, submerged objects, and noise according to ASPRS standards. The data were acquired by Woolpert using a Leica Hawkeye4X system.

Use Cases

• Modeling coastal terrain and bathymetry based on classified ground and bathymetric points.
• Analyzing submerged objects and water surface features based on the corresponding point classifications.
• Filtering and processing lidar point clouds based on the provided noise classifications.
• Creating integrated elevation models for coastal zones based on the combined topographic and bathymetric data.

Strengths

• Data collection spanned a defined period from November 3, 2022 to March III, 2023.
• Points are classified according to ASPRS standards, including specific classes for bathymetry and water surfaces.
• Data were acquired using a specified sensor system (Leica Hawkeye4X).

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.
