Shorelines Extracted from Landsat Imagery: Ship Island, Mississippi

By Kristy K. Guy

Summary

The deployment of Landsat and other earth-observing satellites within the last few decades has provided an opportunity to observe barrier islands at frequent intervals, often many times a year. A variable of persistent interest as a metric for coastal erosion or change is the shoreline. Shorelines derived from imagery have value to resolve coastal changes. This data release includes shoreline positions extracted from Landsat satellite imagery. The shorelines are released in shapefiles with both line and polygon feature types to support a variety of user needs. The data (lines or polygons) are released as individual shapefiles for each sample date and are also released as combined shapefiles with all dates, again to provide users of these data with more options for selecting data of interest. The methods used to identify the shorelines are presented in Guy (2015).
