Broad-scale surveys of vegetation using remote sensing and GIS mapping, coupled with on-the-ground samples in key locations will permit assessment of the effect Grass Carp may have already had on aquatic vegetation communities and establish baseline conditions for assessing future effects.  Existing aerial imagery was used with object-based image analysis to detect and map aquatic vegetation in the eastern basin of Lake Erie.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5a32dd18e4b08e6a89d88682.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7K07351", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5a32dd18e4b08e6a89d88682", "keyword": ["vegetation mapping", "geospatial datasets", "Pennsylvania", "USGS:5a32dd18e4b08e6a89d88682", "Ohio", "Emergent Vegetation", "North America", "Grass Carp", "Great Lakes", "image collections", "Lake County", "Cuyahoga County", "remote sensing", "Chautauqua County", "aquatic vegetation", "Erie County", "ecosystem monitoring", "object-based image analysis", "aerial imagery", "Asian Carp", "invasive species", "habitats", "Ashtabula County", "Submersed Aquatic Vegetation", "geographic information systems", "New York", "Lorain County", "Lake Erie"], "modified": "2023-04-28T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-82.594934313, 41.35737215, -78.853601044, 42.98791231", "theme": ["geospatial"], "title": "Lake Erie, Eastern Basin Aquatic Vegetation"}
