资源简介:
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.
本数据集包含一系列覆盖美国本土(conterminous United States)的栅格数据(raster)。
每张栅格为1千米(km)分辨率的网格,对应1950年至2012年期间的18项精选农业普查(Census of Agriculture)统计指标,且已匹配至土地利用像元。
另有一组包含9项统计指标的补充数据集,以全县域为统计单元,同样以1千米栅格格式提供。
该类栅格数据以ArcGIS栅格(ArcGIS grids)格式发布。
上述统计指标涵盖作物、畜禽、灌溉、化肥及粪肥使用量相关数据。
其中多数统计指标已覆盖该时间段内全部14个农业普查报告年份,具体为1950、1954、1959、1964、1969、1974、1978、1982、1987、1992、1997、2002、2007及2012年。
