2010 Lidar Point Cloud for Lisianski Island, Northwestern Hawaiian Islands

A 2010 lidar survey collected by Aerial Surveying, Inc. for the U.S. Geological Survey and processed by the National Oceanic and Atmospheric Administration provides elevation data for Lisianski Island. The data is in LAS 1.2 format, classified to ASPRS standards for ground, water, and unclassified points. Accuracy statements are based on open terrain, with derived products potentially less accurate in areas of extreme terrain and dense vegetation.

Use Cases

• Modeling sea level rise impacts based on high-resolution coastal elevation data.
• Conducting habitat assessments based on classified ground and water point data.
• Simulating tsunami inundation based on detailed terrain models.
• Validating other remote sensing products using the high-accuracy GPS validation points collected in 2011.

Strengths

• Data collected in 2010 with validation points gathered in April 2011.
• Points are classified to ASPRS standards (Class 1: Unclassified, Class 2: Ground, Class 9: Water).
• Acquired using Riegl 140 and 240 lidar systems from a Beechcraft Queen Air aircraft.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Accuracy is stated for open terrain; derived products may be less accurate in areas of extreme terrain and dense vegetation.
• Column-level documentation is absent; field semantics must be inferred after download.
