Summary

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.

Purpose

These data were collected as part of a large research project that examined the impacts of climate change, sea-level rise, storm waves, and tsunamis on avifauna and their habitat in the Northwestern Hawaiian Islands. Data for this project included a wide range of physical data (coastlines, digital elevation models, bathymetry, predicted wave run-up from storm waves, tsunami high water marks), habitat data (land cover classifications, vegetation maps and monitoring plots), and biological survey data (bird abundance and density, nest census, and habitat surveys). The purpose of digitizing the Laysan coastline was to assess the extent of inundation and habitat loss from passive sea-level rise, wave-driven inundation events, and tsunami events.
