Objectives of the study were to map landcover of water, vegetation, and soil between October 5, 2015, and January 21, 2022, using available imagery from the Sentinel-2 mission. The U.S. Geological Survey's Southwest Biological Science Center (SBSC) and Grand Canyon Monitoring and Research Center (GCMRC) processed 110 Sentinel-2 satellite images representing bottom of atmosphere surface reflectance and classified them within Google Earth Engine (GEE) using threshold values of the Green Normalized Difference Vegetation Index (gNDVI) and its inverse relationship to the Normalized Difference Water Index (NDWI). The classified image data represent the area covered by five distinct landcover types: open water; mixed shallow surface water, saturated soil, and vegetation; dense green vegetation; moist soil with sparse or small vegetation; dry soil with sparse upland vegetation. These data can be used to evaluate the areal extent of each of the landcover types classified in this study as well as changes in the areal extent of these landcover types between October 5, 2015, and January 21, 2022. Additionally, these data may be used as baseline conditions to evaluate future changes in the areal extent of landcover owing to land use changes or climatic fluctuations.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.63dc31a4d34e9fa19a98a385.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P90U1VAM", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_63dc31a4d34e9fa19a98a385", "keyword": ["inlandWaters", "aquatic biology", "imageryBaseMapsEarthCover", "raster data", "soil resources", "Sentinel-2 satellite images", "vegetation", "Green Normalized Difference Vegetation Index", "image collections", "geothermal springs", "Bureau of Land Management Lands", "Nevada", "wetland ecosystems", "image analysis", "wetland complex", "remote sensing", "open water", "moist soil with sparse or small vegetation", "emergent", "habitats", "Department of Defense Lands", "dry soil with sparse upland vegetation", "Fallon", "satellite imagery", "aquatic ecosystems", "biota", "bottom of atmosphere surface reflectance", "ecology", "mixed shallow surface water, saturated soil, and vegetation", "Humboldt salt marsh", "Stillwater Range", "landcover", "hydrology", "land use change", "geothermal resources", "Dixie Valley", "biogeography", "aquatic vegetation", "Naval Air Station Fallon", "gNDVI", "data release", "water resources", "USGS:63dc31a4d34e9fa19a98a385", "classified image data", "upland", "Churchill County", "geoscientificInformation", "shapefile data", "Dixie Meadows", "dense green vegetation"], "modified": "2024-12-30T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-118.0900, 39.7600, -118.0480, 39.8050", "theme": ["geospatial"], "title": "Land cover classification data for wetland complexes at Dixie Meadows, Nevada from October 2015 to January 2022"}
