Historical Disturbance (HDist) is developed from the base annual LF disturbance products, and attribute code system, to represent the history of disturbance for a 10-year span. Each year's disturbance scenarios are checked against time relevant LF vegetation products to check for logical inconsistencies. Errant codes are flagged and updated to a discard code with the remaining disturbance types cross-walked/aggregated to Fuel Disturbance (FDist) types. HDist includes the year of disturbance that is recorded for that pixel. In LF 2022, the time since disturbance code is the same for both HDist and FDist. Starting with LF 2016 Remap, HDist replaced Vegetation Disturbance (VDist) from previous LF versions.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.64f739e4d34ed30c2054464a.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P974JF8W", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_64f739e4d34ed30c2054464a", "keyword": ["biota", "United States", "imageryBaseMapsEarthCover", "LF 2022", "US", "HDist", "geospatial datasets", "LANDFIRE 2022", "USGS:64f739e4d34ed30c2054464a", "hazard preparedness", "AK", "raster digital data", "geographic information systems", "U.S. Forest Service (USFS)", "image collections", "fires", "OCONUS", "U.S. Geological Survey (USGS)", "Historical Disturbance", "remote sensing", "disturbance", "Alaska"], "modified": "2024-04-09T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-179.3173, 48.8767, -122.0000, 71.5478", "theme": ["geospatial"], "title": "LANDFIRE 2022 Historical Disturbance (HDist) AK"}
