Florida\u2019s beaches are highly dynamic coastal features. They are vulnerable to accretion and erosion over time due to human interaction and climate change stressors such as storm activity. \u00a0This research used a well-documented record of historical land surveys and literature, NOAA Historical Surveys, as a basis to calculate the movement of Florida\u2019s coastline throughout history.\u00a0 This dataset of surveys contains digitized coastlines that represent numerous coastline positions between the years 1875 and 2000.\u00a0 The USGS Digital Shoreline Analysis System (DSAS), a software extension to Esri ArcGIS, was used to calculate a long-term change rate from 1875 to 2000 and a short-term change rate from 1950 to 2000.\u00a0 These change rates were overlaid onto georeferenced scans of historical land surveys to map the historical changes that have occurred in Florida\u2019s coastline.<\/p>\n
