Using a combination of laser range-finding, GPS positioning and inertial measurement technologies; Lidar instruments are able to make highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures and vegetation. Breaklines are used in surface models to represent a linear feature. These breaklines were used with lidar for hydro-flattening aquatic features.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P96D56BC", "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.69f263ceb66b017286afb8bd.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_69f263ceb66b017286afb8bd", "keyword": ["Illinois", "Illinois River", "Iowa", "Minnesota", "Mississippi River", "Missouri", "USGS:69f263ceb66b017286afb8bd", "Wisconsin", "aquatic", "backwaters", "breaklines", "digital elevation model", "elevation", "geospatial datasets", "hydroflatten", "lakes", "lidar", "minimum elevation", "ponds"], "modified": "2026-05-11T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-93.2268, 36.9016, -87.5830, 44.9490", "theme": ["geospatial"], "title": "Upper Mississippi River System Lidar Breaklines"}
