SANDS MODIS Analysis of Hurricane Sediment Redistribution

GeoTIFF images from the MODIS sensor were analyzed for sediment redistribution following hurricanes in the Gulf of America. The Geological Survey of Alabama generated this dataset as part of the Sediment Analysis Network for Decision Support project, covering storms from September 2000 to September 2008. Data files include analyzed images, ESRI files for zipped bands or grids, metadata, and storm temporal information.

Use Cases

• Mapping sediment deposition patterns after specific hurricane events using geoTIFF raster data.
• Analyzing seasonal changes in coastal erosion by comparing pre- and post-storm imagery.
• Integrating storm temporal metadata with spatial grids for time-series modeling of sediment transport.
• Using ESRI-compatible files for GIS-based risk assessment and coastal management planning.

Strengths

• Provides an 8-year time series from 2000 to 2008, capturing multiple hurricane seasons.
• Includes both raw geoTIFF imagery and processed ESRI analysis files for direct application.
• Dataset is hosted on multiple authoritative platforms (Data.gov and NASA Earthdata), indicating vetting and importance.

Limitations

• Exact row count, file size, and specific column names are not provided by any source.
• Conflicting last-update dates exist: Data.gov lists 2026 (likely an error), while NASA Earthdata lists 2008.
• License is ambiguously listed as 'other-license-specified' without clear terms.
