Gravity Irrigation Sources on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice IT01
This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject
to the agricultural conservation practice (CPIT01), Gravity Irrigation Source (GI) on agricultural land
by county. Gravity Irrigation Source is described as irrigation "delivered to the farm and/or field by
canals or pipelines open to the atmosphere; and, water is distributed by the force of gravity down
the field by: 1) A surface irrigation system (border, basin, furrow, corrugation, wild flooding, etc.)
or, 2) Sub- surface irrigation pipelines or ditches." (U.S. Department of Agriculture, 1995) This
data set was created with geographic information systems (GIS) and database management tools.
The acres on which GI'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.
