Continually Updated Shoreline Product

Published by Randy Dana, Oregon Coastal Managment Program, GIS Program Leader | State of Oregon | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-01-17
The Oregon CUSP shoreline represents a "best of" attempt to create a continuous Mean High Water Shoreline for use in GIS analysis and inventory work. Whenever possible the Oregon CUSP shoreline references a mean-high water shoreline based upon vertical modelling or image interpretation, using both water level stations and/or shoreline indicators. CUSP is primarily built from LiDAR NGS National Shoreline data for the outer Pacific ocean coast and Oregon Lidar Consortium data for the inner estuarine coast.
