EVC is produced separately for tree, shrub, and herbaceous lifeforms. Training data depicting percentages of canopy cover are obtained from plot-level ground-based visual assessments and lidar observations. These are combined with Landsat imagery (from multiple seasons), to inform models built independently for each lifeform. Tree, shrub, and herbaceous lifeforms each have a potential range from 10% to 100% (cover values less than 10% are binned into the 10% value). The three independent lifeform datasets are merged into a single product based on the dominant lifeform of each pixel. The EVC product is then reconciled through QA/QC measures to ensure lifeform is synchronized with Existing Vegetation Height (EVH).\nIn LF 2024, the vegetation products are updated using rulesets similar to LF 2022 Update (https://landfire.gov/data/lf2022) but only for 2024 disturbances since prior disturbances were brought current using machine learning and 2023 satellite imagery during the LF 2023 Update (https://landfire.gov/data/lf2023). LF uses EVC as an input for LF 2024 Fuel Vegetation Cover (FVC).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P1XVKXRL", "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.694171f1d4be0262a1f66038.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_694171f1d4be0262a1f66038", "keyword": ["CONUS", "Conterminous United States", "Continental U.S.", "EVC", "Existing Vegetation Cover", "LANDFIRE 2024", "LF 2024", "U.S. Forest Service (USFS)", "U.S. Geological Survey (USGS)", "US", "USGS:694171f1d4be0262a1f66038", "United States", "biota", "fires", "geographic information systems", "geospatial datasets", "hazard preparedness", "image collections", "imageryBaseMapsEarthCover", "raster digital data", "remote sensing"], "modified": "2026-03-18T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.9878, 22.7654, -65.2544, 51.6497", "theme": ["geospatial"], "title": "LANDFIRE 2024 Existing Vegetation Cover (EVC) CONUS"}
