This dataset uses lidar derivatives to identify broken forest canopy along the Mississippi River and Illinois River. A broken forest refers to an area that has a canopy height of greater than or equal to 10 meters. From this layer, forest canopy gaps can be identified by locating areas within the broken forest that have at least a 9.144 meter radius, or a 1-tree gap.", "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.5f32adb982cee144fb313832.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5f32adb982cee144fb313832", "keyword": ["Confluence of the Mississippi River to Kampsville, IL", "Illinois", "Missouri", "USGS:5f32adb982cee144fb313832", "canopy gaps", "canopy height model", "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": "-90.632043091002, 38.906106432, -90.482780314, 39.299753926", "theme": ["geospatial"], "title": "Broken Forest Canopy Identified by Lidar for the Alton Reach of the Illinois River"}
