{"@type": "dcat:Dataset", "accessLevel": "public", "accrualPeriodicity": "irregular", "bureauCode": ["005:18"], "contactPoint": {"fn": "Woodruff, Craig, D", "hasEmail": "mailto:craig.woodruff@usda.gov"}, "description": "<p dir=\"ltr\">The variability of vegetation in rangelands can be over generalized in spatial representation and vegetation types mapped by moderate resolution vegetation maps. A high resolution (<1 meter), site specific, vegetation map may better represent the diversity and spatial complexity of rangelands \u2013 a necessity for analyzing pre-fire conditions. We pansharpened two 8-band VNIR Worldview 2 scenes to map pre-fire vegetation in Johnston Draw (1.8 square kilometers) in the Reynolds Creek Experimental Watershed in Southwest Idaho. The two Worldview 2 scenes represent peak greenness (June 14, 2023) and pre-fire (September 23, 2023) conditions with spatial resolutions of 50 centimeters and 42 centimeters, respectively. A prescribed fire burned the area on October 6, 2023. We trained a pixel based random forest classifier to map 10 site specific vegetation classes at a 50-centimeter spatial resolution. We applied a majority filter to remove speckling. Map accuracy was 83.3% when validated using a test set of 54, 30-meter diameter, plots selected to represent the following dominant vegetation types: deciduous/riparian (classes were collapsed into a single class for validation), living juniper, dead juniper, sagebrush, mixed low sage and bunchgrass, bitterbrush, and annual grasses. Barren and water classes were not validated. Training data was developed through a combination of site visit based knowledge and a training set of 30-meter diameter dominant vegetation class plots. The 1.5-billion-dollar cost of fire prevention, suppression, and restoration is stretched thin over the vast area of wildfire occurrence, where site-specific high-resolution vegetation maps are essential to mitigate fire potential and address post fire recovery. In addition to the pre-fire vegetation map a post fire burn product will also be submitted to Ag Data Commons and the related materials will be updated to reflect these complimentary submissions.</p>", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://geodata.nal.usda.gov/geonetwork/srv/api/records/d125cfee-7df5-47a9-8fd6-14186a9f9ac6/formatters/xml", "conformsTo": "https://www.isotc211.org/2005/gmd", "format": "xml", "mediaType": "text/xml", "title": "Geodata ISO 19139 metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/45839475", "format": "tfw", "mediaType": "text/plain", "title": "JohnstonDrawVegetationMap2023.tfw"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/45839478", "format": "tif", "mediaType": "image/tiff", "title": "JohnstonDrawVegetationMap2023.tif"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/45839481", "format": "xml", "mediaType": "text/plain", "title": "JohnstonDrawVegetationMap2023.tif.aux.xml"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/45839484", "format": "ovr", "mediaType": "image/tiff", "title": "JohnstonDrawVegetationMap2023.tif.ovr"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/45839487", "format": "cpg", "mediaType": "text/plain", "title": "JohnstonDrawVegetationMap2023.tif.vat.cpg"}, {"@type": "dcat:Distribution", "downloadURL": "https://ndownloader.figshare.com/files/45839490", "format": "dbf", "mediaType": "application/x-dbf", "title": "JohnstonDrawVegetationMap2023.tif.vat.dbf"}], "identifier": "10.15482/USDA.ADC/25684290.v1", "keyword": ["High Resolution", "Juniper Treatment", "Prescribed fire", "RANGELANDS", "Random Forest", "Remote Sensing", "Vegetation  mapping"], "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2025-11-22", "programCode": ["005:040"], "publisher": {"@type": "org:Organization", "name": "Agricultural Research Service"}, "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[-116.8034633, 43.1345622], [-116.8036544, 43.1195483], [-116.7739607, 43.1193418], [-116.7737624, 43.1343556], [-116.8034633, 43.1345622]]]}", "temporal": "2023-06-14/2023-09-23", "theme": ["geospatial"], "title": "Johnston Draw (Idaho) High Resolution Pre-Fire Vegetation Map 2023"}
