Sea-Level Rise Visualization for Alabama and Mississippi
The interactive sea-level rise visualization tool results from a collaborative effort between NOAA's Coastal Services Center, USGS WARC, and USGS Mississippi Water Science Center. The tool illustrates the scale of potential flooding, but not the exact location, and does not account for erosion, subsidence, sediment accretion, or future construction.
USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations.
Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.
