National Assessment of Shoreline Change: A GIS Compilation of Vector Shorelines and Associated Shoreline Change Data for the Pacific Northwest Coast


Introduction

Skip past contents information This compilation of open-ocean, sandy shorelines for the Pacific Northwest (Washington and Oregon states for the purpose of this report) is part of a series that includes already published shoreline data for the Gulf of Mexico, Southeast Atlantic, California, New England, Mid-Atlantic, and Hawaiian coasts (Morton and others, 2004; Morton and Miller, 2005; Hapke and others, 2006, 2010; Fletcher and others, 2012). Alaska has been identified as an area for future shoreline change studies. The Pacific Northwest shoreline data, like the New England and Mid-Atlantic data, incorporate all available shorelines that meet minimum quality standards for resolution and positional accuracy. The historical shorelines cover a variety of time periods ranging from 1868 to 1999, and the modern, light detection and ranging (lidar) shoreline was derived from data collected in 2002.
