While many information needs can be met by using these data separately, in many cases seamless elevation data across the river and its floodplain are needed. This seamless elevation surface was generated by merging lidar (i.e., floodplain elevation) and bathymetry data. Merging the data required special processing in the areas of transition between the two sources of data.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7057CZ3", "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.5589ae19e4b0b6d21dd63942.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5589ae19e4b0b6d21dd63942", "keyword": ["Illinois", "Illinois River", "Iowa", "Minnesota", "Mississippi River", "Missouri", "USGS:5589ae19e4b0b6d21dd63942", "Upper Mississippi River System", "Wisconsin", "bathymetry", "elevation", "imageryBaseMapsEarthCover", "lidar", "topobathy", "topographic maps"], "modified": "2026-06-22T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-93.5376, 36.7389, -88.0225, 45.0114", "theme": ["geospatial"], "title": "Upper Mississippi River System Topobathy"}
