Shoreline Shapefiles

A digital vector shoreline (land/water interface) was manually digitized from the one-meter pansharpened multispectral IKONOS imagery to provide accurate, up-to-date shoreline data. Those areas of the coastline that were obscured by cloud cover were derived from United States Geological Survey (USGS) Digital Raster Graphics (DRGs).
