Pre- and Post-Hurricane Lidar Surveys of a Texas Barrier Island

Central Texas coast airborne lidar surveys conducted by the Bureau of Economic Geology, University of Texas at Austin. The dataset includes two surveys from February 27, 2024, and August 1, 2024, capturing conditions before and after Hurricane Beryl made landfall. Data files include LAS point clouds and wrack line shapefiles.

Use Cases

• Modeling coastal change and sediment transport based on pre- and post-storm lidar elevation data.
• Analyzing the distribution and movement of marine debris based on mapped wrack line features.
• Assessing hurricane impacts on barrier island morphology using high-resolution topographic data.

Strengths

• Two temporally distinct surveys provide a direct before-and-after comparison of a hurricane impact.
• Data collection by the Bureau of Economic Geology, University of Texas at Austin, suggests authoritative sourcing.
• Includes both raw LAS point cloud data and processed wrack line shapefiles for different analysis levels.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data volume are unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update is dated 2026-04-27.
