The following list organizes data sets developed by the Southwest Washington Coastal Erosion Study into common themes.  Metadata is currently being developed to document processing and data development techniques.  Files listed in the Regional data sets and Shorelines sections are available as ArcInfo export files (*.e00) or ArcView shapefiles (*.shp).  The beach profiles are available as text files (*.txt).  For more information contact George Kaminsky.
