Likely Extent of Agricultural Drainage in the U.S. Midwest

This dataset provides 30 m resolution raster layers of the likely extent of drained agricultural lands in the U.S. Midwest based on soil and land use, and a file geodatabase with tables summarizing the extent by state, county, and HUC8 watershed boundary.

本数据集提供了基于土壤和土地利用情况，美国中西部可能排干农业用地范围的高达30米分辨率的栅格图层，并附带一个包含按州、县和HUC8流域边界汇总范围的文件地理数据库。
