Gravity Irrigation Source is described as irrigation \"delivered to the farm and/or field by \ncanals or pipelines open to the atmosphere; and, water is distributed by the force of gravity down \nthe field by: 1) A surface irrigation system (border, basin, furrow, corrugation, wild flooding, etc.) \nor, 2) Sub- surface irrigation pipelines or ditches.\" (U.S. Department of Agriculture, 1995)  This \ndata set was created with geographic information systems (GIS) and database management tools. \nThe acres on which GI's are applied were totaled at the county level in the tabular NRI database \nand then apportioned to a raster coverage of agricultural land within the county based on the \nEnhanced National Land Cover Dataset (NLCDe) 1-kilometer resolution land cover grids \n(Nakagaki, 2003). Federal land is not considered in this analysis because NRI does not \nrecord information on those lands.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9ZWQDQ8", "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.709bfbc6-269d-450c-bb1c-4967fd334978.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_709bfbc6-269d-450c-bb1c-4967fd334978", "keyword": ["Agricultural Practices", "Gravity Irrigation", "National Resources Inventory", "USGS:709bfbc6-269d-450c-bb1c-4967fd334978", "environment", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.8877, 22.8607, -65.3468, 51.6088", "theme": ["geospatial"], "title": "Gravity Irrigation Sources on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice IT01"}
