SWCES Project Overview

Bathymetric Data

Edited and Combined Survey Data and Grids

The following digital data sets are composites of historical and modern hydrographic sounding data within the Columbia River littoral cell for three unique regions (entire study area, Columbia River subset, Grays Harbor subset) and four unique Eras (1-4). Except for the estuary data, the individual surveys have been evaluated for errors and inconsistencies and the data points removed. See the Process Step section in the metadata for specific information. Original data was reprojected to Washington Stateplane, FIPS 4602, meters. Attributes inlcude easting, northing, depth-navd(m), depth-mllw(m), and original survey name. The composites for Columbia River (cr) and Grays Harbor (gh) were compiled by Maarten Buijsman and are the data sets used for the sediment budget analysis. They also include CPS and shoreline data.

Individual Hydrographic Survey Data

The following digital data sets include historical hydrographic sounding data collected by either the National Ocean Service (formerly the U.S. Coast and Geodetic Survey) or the US Army Corps of Engineers. Some of the surveys have been evaluated for errors and inconsistencies. Except for the Era 1 surveys, soundings with questionable depths are included in the following data sets, but their cartographic codes have been changed. Cartographic codes of 711 are considered valid sounding data while those with codes other than 711 were determined to be somehow in error. See the Process Step section in the metadata for specific information. The original data sets have been reprojected to Washington Stateplane, FIPS 4602, meters. Attributes include easting, northing, depth-navd(m), depth-mllw(m), cartographic code, survey name, and survey year.

Data is divided by:
