SANDS MODIS Gulf Coast Sediment Imagery for Hurricane Analysis

SANDs provides 8 years of MODIS satellite imagery, from September 2000 to September 2008, focused on the Gulf of America coastline. NASA created this dataset to analyze sediment redistribution after hurricanes using Terra and Aqua satellite reflectance bands 8-16. The data is subsetted to a specific coastal region spanning 31-27N latitude and 90-84.25W longitude.

Use Cases

• Analyzing pre- and post-hurricane sediment concentration using MODIS reflectance bands.
• Mapping seasonal changes in coastal erosion and sedimentation patterns.
• Modeling sediment transport dynamics along the Alabama and Florida Gulf coast.
• Supporting decision-making for coastal management and restoration projects.

Strengths

• Covers an 8-year time range specifically targeting storm seasons from 2000 to 2008.
• Provides spatially subsetted data for a focused study area on the Gulf coast.
• Utilizes calibrated MODIS reflectance bands (8-16) from both Terra and Aqua satellites.
• Cross-platform presence on Data.gov and NASA EarthData indicates established importance.

Limitations

• Row count, dataset size, and specific column names are not provided by any source.
• Conflicting last update dates: Data.gov lists 2026-03 12, while NASA EarthData lists 2008-09-09.
• Data is limited to daytime images and a historical period ending in 2008.
