NOAA NGS LIDAR: Barnegat Light, New Jersey Topobathy Point Cloud

2013 NOAA NGS LIDAR of New Jersey: Barnegat Light is a topobathy point cloud dataset collected by the National Oceanic and Atmospheric Administration's National Geodetic Survey. The data was acquired over two days in September 2013 and includes classified points for ground, water, bathymetry, and noise, along with lidar intensity and encoded RGB values. It is stored in LAS 1.2 format and covers the Barnegat Light area in Ocean County, New Jersey.

Use Cases

• Generate high-resolution coastal elevation models based on classified ground and bathymetric points.
• Analyze coastal feature changes using the lidar intensity values and RGB image data.
• Train models for automated point cloud classification using the provided class labels (e.g., ground, water, bathymetric lidar).

Strengths

• Data includes multiple classified point types (unclassified, ground, water, bathymetric lidar, noise) for detailed analysis.
• Contains both elevation data and supplementary attributes like lidar intensity and encoded RGB values.
• Acquisition dates (20130923 - 20130924) and specific geographic location (Barnegat Light, NJ) are explicitly documented.

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.
