Lidar Topographic Data for Fire Island, NY and Cape May, NJ from 2011

2011 NOAA National Geodetic Survey lidar data collected for Fire Island, New York, and Cape May to Absecon Inlet, New Jersey. The data includes topographic point clouds in LAS 1.2 format, classified as unclassified, ground, and water, along with lidar intensity and encoded RGB values. Fire Island data was collected on November 25, 2011, and the New Jersey data was collected on July 16, 2011.

Use Cases

• Coastal erosion modeling based on ground-classified topographic data.
• Flood risk assessment based on terrain elevation and water classification.
• 3D terrain visualization based on point cloud and RGB image values.
• Shoreline mapping based on classified ground and water data points.

Strengths

• Data follows ASPRS classification standards for point clouds.
• Includes lidar intensity values and encoded RGB image values.
• Collection dates are explicitly stated for each geographic area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from 2011; freshness should be verified for current applications.
