Aerial surveys document coastal changes caused by Hurricane Katrina after its August 29, 2005 landfall in Louisiana. Data includes video, photography, and laser altimetry collected on August 31 and September 1, 2005 for comparison with pre-storm conditions. The U.S. Geological Survey, NASA, the U.S. Army Corps of Engineers, and the University of New Orleans collaborated on this research project.
Use Cases
- Quantify beach erosion and overwash deposition by comparing pre- and post-storm laser altimetry elevation data.
- Map spatial variability of island breaching using aerial photography and video imagery from the surveys.
- Refine storm impact models by correlating observed coastal change magnitudes with specific storm parameters.
- Support disaster recovery and erosion mitigation planning for agencies using geospatial change analysis.
Strengths
- Data captured immediately after landfall (August 31-September 1, 2005), providing a timely post-event snapshot.
- Multimodal collection includes aerial video, still photography, and laser altimetry for complementary analysis.
Limitations
- Sample size and specific row/column counts for the derived datasets are unknown.
- Geographic coverage is limited to the surveyed areas affected by Hurricane Katrina, not a global sample.
- Temporal coverage is focused on a single event, lacking long-term time-series data.
