Barrier
Island maps were derived from NOS shorelines. First, a selection of
barrier-island NOS shoreline of the U.S. Gulf of Mexico was made. Shorelines
were dissolved and gaps between lines were closed. Line data was transformed to
polygon data using ET Geowizard ArcGIS extension. Final polygons were edited as
necessary and small residual features were removed. Barrier names were assigned
using GNIS and R.A. Davis' book as resources.
