Description
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.
