Himmelstoss, E.A., Kratzmann, M.G., and Thieler, E.R., 2017, National assessment of shoreline change – A GIS compilation of updated vector shorelines and associated shoreline change data for the Gulf of Mexico: U.S. Geological Survey data release, https://doi.org/10.5066/F78P5XNK.

This dataset includes shorelines from 146 years ranging from 1855 to 2001 in the Florida north coastal region from Bald Point State Park to the Alabama border. Shorelines were compiled from topographic survey sheets (T-sheets; National Oceanic and Atmospheric Administration (NOAA), NOAA/Florida Department of Environmental Protection (FLDEP)), aerial photographs (FLDEP), and lidar data (United States Geological Survey/National Aeronautics and Space Administration). Historical shoreline positions serve as easily understood features that can be used to describe the movement of beaches through time. These data are used to calculate rates of shoreline change for the U.S. Geological Survey's (USGS) National Assessment of Shoreline Change Project. Rates of long-term and short-term shoreline change were generated in a GIS using the Digital Shoreline Analysis System (DSAS) version 4.3. DSAS uses a measurement baseline method to calculate rate-of-change statistics. Transects are cast from the reference baseline to intersect each shoreline, establishing measurement points used to calculate shoreline change rates.
