Mapping was conducted with a recreational grade side-scan sonar unit from the river mouth at Lake Erie (river kilometer (rkm) 0) to near the confluence of the Little Cuyahoga River (rkm 71). Side-scan sonar images were georectified in a post-processing software and substrate patches were manually digitized and classified in a geographic information system (GIS). Ground-truthing data were collected following side-scan sonar surveys to determine the accuracy of patch classifications. Substrate composition at ground-truthing locations was determined through visual assessments when feasible and assessed with tactile feel when water depth or clarity prevented visual assessment. Substrate patch types classified from side-scan sonar imagery are provided as polygon shapefiles and ground-truthing observations are provided as point shapefiles.", "distribution": [{"@type": "dcat:Distribution", "description": "A point shapefile with surficial substrate composition at locations used to ground truth substrate classifications derived from side-scan sonar imagery.", "downloadURL": "https://iris.fws.gov/APPS/ServCat/DownloadFile/267799?Reference=178665", "format": "zip", "mediaType": "application/zip", "title": "cuyahogaSubstrateGroundTruth_2021.zip"}, {"@type": "dcat:Distribution", "description": "Metadata describing the data collection methods, data processing methods, fields contained within the data sets, and the spatial information associated with the data.", "downloadURL": "https://iris.fws.gov/APPS/ServCat/DownloadFile/267802?Reference=178665", "format": "xml", "mediaType": "application/xml", "title": "cuyahogaRiver_substrateMap_metadata_13Feb2025.xml"}, {"@type": "dcat:Distribution", "description": "Polygon shapefile of substrate patches identified and digitized from side-scan sonar imagery in the Cuyahoga River.", "downloadURL": "https://iris.fws.gov/APPS/ServCat/DownloadFile/267798?Reference=178665", "format": "zip", "mediaType": "application/zip", "title": "cuyahogaSideScanClassification_17Nov2022.zip"}], "identifier": "http://datainventory.doi.gov/id/dataset/FWS_ServCat_178665", "issued": "2025-02-13T00:00:00Z", "keyword": ["Cuyahoga River", "General: Geology and Soils | Geomorphology | Stream/River Processes", "General: Management | Habitat Management | Habitat Models", "Lake Erie", "Lake Sturgeon", "Ohio", "biota", "habitat suitability indices", "inland waters", "substrate"], "landingPage": "https://iris.fws.gov/APPS/ServCat/Reference/Profile/178665", "modified": "2025-02-13T00:00:00Z", "programCode": ["010:028", "010:094"], "publisher": {"@type": "org:Organization", "name": "U.S. Fish and Wildlife Service"}, "spatial": "-81.73,41.09,-81.52,41.51", "temporal": "2021-05-24/2022-11-11", "theme": ["geospatial"], "title": "Surficial Substrates in the Cuyahoga River, Ohio, 2021"}
