Gravity and Pressure Irrigation on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice IT03

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the agricultural conservation practice (CPIT03), Gravity and Pressure Irrigation Source (GPI) on agricultural land by county. Gravity and Pressure Irrigation Source are described as a "combination of Gravity and Pressure Irrigation." (U.S.

Department of Agriculture, 1995) This data set was created with geographic information systems (GIS) and database management tools. The acres on which GPI's are applied were totaled at the county level in the tabular NRI database and then apportioned to a raster coverage of agricultural land within the county based on the Enhanced National Land Cover Dataset (NLCDe) 1-kilometer resolution land cover grids (Nakagaki, 2003). Federal land is not considered in this analysis because NRI does not record information on those lands.
