Tropical cyclones have significantly altered normal coastal processes and characteristics in the Gulf region through sediment disturbance. The Sediment Analysis Network for Decision Support (SANDS) project is addressing sediment redistribution issues by producing a suite of decision support products, derived from satellite observations from MODIS, Landsat and SeaWiFS instruments, for assessment ... and monitoring of suspended sediment and sediment deposition in the north central Gulf of Mexico region. These products will support resource management, planning, and decision making activities in the Gulf of Mexico. The project will also facilitate delivery of the resulting products to end users by making them available through a SANDS portal hosted at the Geological Survey of Alabama (GSA) and through NASA’s Global Hydrology Resource Center (GHRC).
The Sediment Analysis Network for Decision Support (SANDS) will analyze these GeoTIFF images for sediment redistribution after a hurricane on the Gulf coast and then create a product from that. This dataset consists of geoTIFF images provided to the Geological Survey of Alabama for their analysis. Only daytime images for MODIS Aqua Reflectance bands 8-16 for H10V6 and H10V5 were downloaded and used to create the geoTIFF images for each storm. These are seasonal data for storms from 2001-2008.
