Description: This dataset was primarily made by combining two shoreline datasets from NOAA: Electronic Navigational Charts (ENC) from the Office of Coast Survey, and the Continually Updated Shoreline Product (CUSP) from the National Geodetic Survey. A third dataset, (a MHHW shoreline developed by the University of Washington Olympic Natural Resources Center) was also used for Willapa Bay.Typically the CUSP data was used where available, and the ENC data was used otherwise. The ONRC MHHW shoreline was used for Willapa Bay. Where line segments were missing, or where two shorelines did not connect, artificial line segments were added.-----CUSP-----Data was downloaded as a shapefile."The shoreline is a representation based on an office interpretation of imagery or derived from Lidar. Shoreline vectors were verified with contemporary imagery. Sources of non-NOAA vector shoreline included U.S. Fish and Wildlife Service, North Carolina Department of Environment and Natural Resources, and U.S. Geological Survey. Non-NOAA imagery sources for interpreting shoreline included USDA-FSA Aerial Photography Field Office, ESRI Imagery World 2D (USGS, U.S. Geological Survey, and U.S. Department of Agriculture), Bing Maps Imagery Service, and Google Earth (TerraMetrics and DigitalGlobe)."-----ENC-----Data was downloaded in the International Hydrographic Organization S-57 Standard format. Data exists at multiple resolutions. All data used to create this feature class were one of the following resolutions:3 is for coastal charts with scales ranging from 1:150,001 - 1:600,0004 is for approach charts with scales ranging from 1:50,001 - 1:150,0005 is for harbour charts with scales ranging from 1:50,000 or larger.Where level 5 data was available, it was used. If level 5 data was not available, level 4 data was used where available. And where level 5 and level 4 data were not available, level 3 data was used.The "LNDARE Polygon" features were used to determine the shoreline.FURTHER INFORMATIONFrom: http://www.nauticalcharts.noaa.gov/mcd/learnnc_shoreline.html"The shoreline shown on nautical charts represents the line of contact between the land and water at a selected vertical datum. In areas affected by tidal fluctuations, this is usually the mean high-water line. In confined coastal waters of diminished tidal influence, a mean water level line may be used. The shoreline of interior waters (rivers, lakes) is usually a line representing a specified elevation above a selected datum.""NOAA’s National Geodetic Survey (NGS) conducts high accuracy photogrammetric surveys that are used as a basis to update NOAA charts. NGS may also identify shoreline changes from satellite imagery. Some shoreline updates are received through the U.S. Army Corps of Engineers when construction permits have been issued. The shoreline on any particular NOAA nautical may be based on a patchwork of surveys that have been conducted over many years. "-----ONRC-----Though new and old features were removed, added, or modified, the currentness should still be considered as 2008. This is because many such features, natural or manmade, may still exist in this dataset. Ground truthing has not been done nor has checking for the possible presence of these features by other means due to time constraints.In areas of the intertidal zone that hosted Spartina, elevations will be lower now than they were when the dataset was originally produced. This is due to the success of the Spartina Eradication and Control Project which succeded in removing the Spartina epiflora (I'm specific here because other epiflora were *not* removed. Thus, these areas are now exposed to erosional forces not experienced previously.This dataset does *not* extend beyond saltwater influence as this dataset is intended to represent a marine shoreline. Saltwater influence is not the same as tidal influence, as freshwater influx may "back up" during rising tides and this affect is felt farther upstream than tidal mixing of salt and fresh water.Tides become more extreme, and undergo greater delays relative to the distance from the mouths of restricted waterways. These effects attenuate as tidal influence wanes at the upstream end of estuarine reaches.Placement accuracy of MHHW is more problematic near the mouth of Willapa Bay, though strand lines continue to be a good guide there.

Description: Beneficial Use Designations for marine waters, as defined in WAC 173-201A-612 for the Washington State Coast.Derived from ECY coastal WRIAs. NOAA Electronic Navigation Chart Level 5 polygons were used to erase land areas. The remaining water areas were divided into zones.

Description: Data provided to UW. Datasets from multiple sources were combined, and had attributes added. Contains the following where available: Owner Name, Owner Address, Oyster Bed Class, Gibbs Number, and Parcel Number. All oyster beds were assigned an owner class based on the owner name. Possilble values include: Public, Private, Tribal, or Unknown.

Description: This dataset was made from the MSP_Combined_Shoreline dataset, the U.S. Fish and Wildlife Service and (or) the National Wetlands Inventory, and other boundary lines.Classification of the various polygons was based on Pacific County source maps.EDShoreline and EDMarineZone fields are defined in a domain in the database.
Description: This dataset was made from a combined shoreline dataset and other boundary lines. The combined shoreline was made using NOAA Electronic Navigational Charts (ENC) from the Office of Coast Survey, the NOAA Continually Updated Shoreline Product (CUSP) from the National Geodetic Survey, and a MHHW shoreline for Willapa Bay developed by the University of Washington Olympic Natural Resources Center. The other boundary lines are: the border with Canada is 49 degrees north; the border with Oregon that is not the Columbia River is 46 degrees north; the border with Idaho is based on data from the National Hydrology Dataset (the Snake River NHDArea and a line directly north from the confluence of the Snake and Clearwater Rivers).More information about the combined shoreline can be found in the feature class MSP_combined_shoreline.
