Predictions were made at eight time periods (2001, 2004, 2006, 2008, 2011, 2013, 2016, and 2019) according to changes in landcover using the National Land Cover Database (NLCD). The Chessie BIBI data used were provided by the Interstate Commission on the Potomac River Basin. Uncertainty was calculated using model prediction intervals.\u202fFor complete data descriptions and data interpretation see associated publication (Maloney et al., 2022).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9YKRPO1", "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.622f9e7cd34ec9f19eeaa61c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_622f9e7cd34ec9f19eeaa61c", "keyword": ["Chesapeake Bay watershed", "Delaware (state)", "District of Columbia (national district)", "Maryland (state)", "New York (state)", "Pennsylvania (state)", "USGS:622f9e7cd34ec9f19eeaa61c", "Virginia (state)", "West Virginia (state)", "benthic macroinvertebrates", "habitats", "natural resource assessment", "prediction", "random forest"], "modified": "2022-07-13T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-80.6538, 36.5793, -74.4593, 43.0773", "theme": ["geospatial"], "title": "Model predictions of biological condition for small streams in the Chesapeake Bay Watershed, USA"}
