This dataset uses lidar derivatives to identify forest canopy gaps along select portions of the Mississippi River and Illinois River. USACE will use this dataset to select field sites to collect data in forest canopy gaps. This will also serve as the baseline for long-term forest canopy gap study.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9BLTSTZ", "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.5f329cb382cee144fb30dd19.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5f329cb382cee144fb30dd19", "keyword": ["Illinois", "Iowa", "Navigational Pool 13", "USGS:5f329cb382cee144fb30dd19", "Wisconsin", "canopy gap", "canopy height model", "flood inundation", "forest", "forest resources", "forestry", "land cover/land use", "lidar"], "modified": "2026-01-28T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-90.431312896004, 41.895484405, -90.054444651001, 42.272046912", "theme": ["geospatial"], "title": "Forest Canopy Gaps Identified by Lidar for Navigational Pool 13 of the Mississippi River"}
