The format of this data is a grid with each cell covering 0.5 meter by 0.5 meter.  The elevation value \n(North American Vertical Datum, NAVD88) represented by each cell is the most probable elevation for that cell \nbased on calculated Total Propagated Uncertainty (TPU) as calculated in Caris HIPS and SIPS software.  Calculated \nTPS values are then used by Caris to create a Combined Uncertainty and Bathymetric Estimator (CUBE) surface.  \nThe surface grid was used to export the cell centroid position (Northing, Easting in UTM zone 14 North, in meters) \nalong with the cell elevation (referenced to NAVD88, in meters) to create the text file.  The data were collected by \nthe U.S. Geological Survey in cooperation with the Environmental Protection Agency (EPA) and the Omaha Public \nPower District (OPPD).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9IZVI3G", "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.618a6405-e959-425d-9f4e-4da9472962b1.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_618a6405-e959-425d-9f4e-4da9472962b1", "keyword": ["Cass County", "Fremont County", "Iowa", "Missouri River", "Nebraska", "USGS:618a6405-e959-425d-9f4e-4da9472962b1", "bathymetry", "environment", "geoscientificInformation", "inlandWaters", "multibeam sonar", "terrain", "topography"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "95.84190, 40.80235, 95.84607, 40.80600", "theme": ["geospatial"], "title": "Missouri River bed elevations at pipeline crossing near Union, Nebraska surveyed during 2011 flood on July, 27"}
