NOAA Topobathy Lidar Data for West Biscayne Bay, Florida

2018 NOAA NGS Topobathy Lidar data collected for West Biscayne Bay, Florida. The data were collected by the National Oceanic and Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl VQ880G system. The data are in LAS 1.2 format and include classifications such as ground, bathymetric point, and submerged object.

Use Cases

• Modeling coastal erosion and sediment transport based on ground and bathymetric point classifications.
• Analyzing submerged object detection and mapping based on the encoded classification for submerged objects.
• Creating digital elevation models for coastal zones based on combined topographic and bathymetric lidar points.
• Studying coastal habitat changes based on the intensity values and RGB image data potentially encoded in the point cloud.

Strengths

• Data collected by NOAA's National Geodetic Survey, a federal authoritative source.
• Includes both topographic and bathymetric (topobathy) data in a single survey.
• Points are classified according to ASPRS standards, including ground, bathymetric, and submerged object categories.

Limitations

• Column-level documentation and sample data are unavailable, requiring manual inspection after download.
• Row count and total file size are unknown, limiting suitability assessment for large-scale projects.
• The description does not specify the exact spatial resolution or point density of the lidar survey.
