National 1-kilometer rasters of selected Census of Agriculture statistics allocated to land use for the time period 1950 to
2012
Dataset Identification:
Resource Abstract:
This dataset consists of a series of rasters covering the conterminous United States. Each raster is a one kilometer (km)
grid for 18 selected Census of Agriculture statistics mapped to land use pixels for the time period 1950 to 2012. A supplemental
set of 9 statistics mapped at the entire county level are also provided as 1-km rasters. The rasters are posted as ArcGIS
grids. The statistics represent values for crops, livestock, irrigation, fertilizer, and manure usage. Most statistics are
mapped for all 14 Census of Agriculture reporting years in that time frame: 1950, 1954, 1959, 1964, 1969, 1974, 1978, 1982,
1987, 1992, 1997, 2002, 2007, and 2012.

purpose:
The purpose of this dataset is to provide GIS-ready national rasters of county-level agricultural statistics, and where possible
to map those statistics to appropriate land use pixels. Mapping to land use pixels is a form of dasymetric mapping, which
has the effect of masking out areas that are unlikely to have an agricultural component (for example, water or urban pixels).
This improves the accuracy of zonal (for example, watershed)-based statistics calculated from the datasets. The 9 rasters
not mapped to land use pixels are provided as a convenience.
