The survey was from river mile (RM) 130 to 142 on the Snake River, \nand from RM 0 to 2 on the Clearwater River areas of Lower Granite Reservoir. The survey mapped \nthe part of the river that was accessible to the boat and the echosounder equipment, but very \nshallow areas along the banks that were inaccessible or too shallow to be measured with \nechosounder equipment were not mapped. The survey was conducted in 1-mile segments, \nand the data were combined to provide a continuous digital elevation dataset of the reservoir \nwithin the limitations of the project. The elevation points in the dataset were referenced to the \nUSACE established benchmarks using the real-time kinematic-global positioning system \n(RTK-GPS); therefore, point elevations were unaffected by reservoir stage changes.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9PY8STF", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.2b27f810-75a9-4104-800e-0548130b5528.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_2b27f810-75a9-4104-800e-0548130b5528", "keyword": ["Barge", "Bathymetric", "Bathymetry", "Clearwater River", "Dam", "Dune", "Hydrographic", "ID", "Idaho", "Lower Granite Reservoir", "Multibeam", "NORTH AMERICA", "Orthometric", "Ripple", "Salmon", "Snake River", "Sounding Point", "Survey", "Topographic", "UNITED STATES", "UNITED STATES OF AMERICA", "USGS:2b27f810-75a9-4104-800e-0548130b5528", "bedforms", "elevation", "environment", "geoscientificInformation", "imageryBaseMapsEarthCover", "inlandWaters", "location", "oceans", "structure", "unconsolidated deposits"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-117.21741704, 46.38479878, -116.99960711, 46.43680966", "theme": ["geospatial"], "title": "Bathymetry Data for Portions of Lower Granite Reservoir and Vicinity, Washington and Idaho, 2009-10"}
