Laysan Island coastline 2010May18

This dataset contains a screen-digitized coastline for Laysan Island based on a DigitalGlobe WorldView-2 satellite image taken on May 18, 2010. After digitization the coastline was corrected for tide using a 1-meter digital elevation model (DEM). It was also smoothed in ArcGIS 10 to remove some of the inherent jaggedness from the point-by-point digitizing process. Like most of the Northwestern Hawaiian Islands, this coastline is very dynamic and changes considerably from season to season, year to year, as erosion and deposition of sand are in flux.
