Landsat Sediment Analysis for Gulf Coast Storms 2001-2008

Landsat satellite imagery from the Gulf of America coastline in Alabama and Florida was analyzed for sediment redistribution following hurricanes. The dataset, produced by NASA's Sediment Analysis Network for Decision Support (SANDS) project, contains seasonal GeoTiff images and ESRI files from Landsat 5 and 7 satellites. It covers storms occurring between 2001 and 2008.

Use Cases

• Analyzing shoreline change using pre- and post-storm GeoTiff image bands.
• Modeling sediment transport patterns from hurricane impacts using gridded ESRI data.
• Studying seasonal sedimentation variability along the Gulf Coast with temporal storm information.
• Assessing coastal erosion by comparing Landsat imagery across the 2001-2008 time range.

Strengths

• Data is derived from established Landsat 5 and 7 satellite imagery, providing standardized geospatial inputs.
• Covers a multi-year period (2001-2008) for analyzing seasonal storm impacts.
• Includes processed analysis files alongside raw bands and grids, supporting multiple levels of investigation.

Limitations

• Key metadata conflicts exist: the last updated date is listed as both 2008-09-08 and 2026-03-12 across platforms.
• Specific column names, row counts, and dataset size are not provided by any source.
• The exact license terms under 'other-license-specified' are not detailed.
