The BLM OR Ocean Map Service represents the Pacific Ocean's shoreline from the area of Canada's Vancouver Island to south of San Francisco Bay. The data comes from the U.S. National Oceanic and Atmospheric Administration's (NOAA) Continually Updated Shoreline Product (CUSP). The service does not include bays and inlets available in CUSP, instead cutting across the natural mouth or end of jetties. For a complete description of the data, consult the Administrative Unit Boundaries Spatial Data Standard at https://www.blm.gov/about/data/oregon-data-management.

The BLM OR Ocean Map Service is created from administrative_units.gdb\OCEAN_POLY and OCEAN_ARC. This map service has three feature level scale dependencies that limit the number of viewable offshore islands. The Islands Shoreline layer displays major islands in the ocean at a scale out beyond 1:2,999,999, major and large islands in the ocean at a scale of 1:999,999 to 1:2,999,999 and island features still visible above the water at mean high at a scale in beyond 1:999,999. The field SHORELINE, in the Mainland Shore layer, can be used to control visibility of the Pacific Ocean’s shoreline along the Oregon, Washington, California and Canadian coasts.
