Shoreline positions were collected prior to and following Hurricane Irma along the sandy shorelines of Florida and Georgia. Shoreline positions from the mid-1800s through 2018 were used to update the shoreline change rates for Florida and Georgia using the Digital Shoreline Analysis System (DSAS) software. The shoreline positions and updated shoreline change rates calculated by the USGS provide actionable information to homeowners, coastal communities, and managers of public and private properties. This information can be used to improve resilience to erosion hazards. This information can now also be used by DSAS to estimate the future shoreline position. The forecasted shoreline position for the year 2031, and its estimated uncertainty, are provided in this data release. This forecast should be treated with extreme caution. The method used by DSAS to produce it is still preliminary. Initial testing of the method has shown that forecasts can be highly inaccurate, especially in dynamic areas (for example, near inlets). The degree of error in the forecasted shoreline position may be larger than the estimated uncertainty.

Are there legal restrictions on access or use of the data?Access_Constraints: None
Use_Constraints:These data were automatically generated using the DSAS version 5 software application and should only be used for purposes explicitly stated by the originating organization. The method used to calculate these forecasts is still being tested for accuracy. These forecasts should be handled with extreme caution and are likely inaccurate in many areas, especially near inlets.
