Gridded time-series data of the US cropland distribution from 1850 to 2016

We reconstructed the cropland density maps by harmonizing multiple sources of inventory data and high-resolution satellite images. The time-series gridded data depicts the distribution and percentage of cultivated land each year (excluding summer idle/fallow, cropland pasture). The reconstructed annual cropland percentage maps were at 1 km×1 km resolution covering the conterminous U.S. spanning from 1850 to 2016.
