Summary

Sandy ocean beaches in the United States are popular tourist and recreational destinations and constitute some of the most valuable real estate in the country. The boundary between land and water along the coastline is often the location of concentrated residential and commercial development and is frequently exposed to a range of natural hazards, which include flooding, storm effects, and coastal erosion. In response, the U.S. Geological Survey (USGS) is conducting a national assessment of coastal change hazards. One component of this research effort, the National Assessment of Shoreline Change Project, documents changes in shoreline position as a proxy for coastal change. Shoreline position is an easily understood feature representing [...]

Purpose

This dataset includes a reference baseline used by the Digital Shoreline Analysis System (DSAS) to calculate rate-of-change statistics for the Florida west coastal region from Anclote Key to Estero Island. This baseline layer serves as the starting point for all transects cast by the DSAS application. The transects intersect each shoreline and establish measurement points used to calculate shoreline-change rates. Rates of long-term and short-term shoreline change were generated in a GIS using the DSAS version 4.3- An ArcGIS extension for calculating shoreline change: U.S. Geological Survey Open-File Report 2008-1278, Thieler, E.R., Himmelstoss, E.A., Zichichi, J.L., and Ergul, Ayhan.
