Mapping of 30-meter resolution tile-drained croplands using a geospatial modeling approach

摘要

Input data to AgTile-US GIS model for generating gridded tile drainage data for the U.S. (a) County-level tile drainage area (ha) from USDA Census of Agriculture 2017, (b) National Land Cover Database (NLCD) 2016 cropland mask at 30 m resolution, (c) Shuttle Radar Topography Mission Digital Elevation Model derived slope (%) at 30 m, and (d) Spatial pattern of soil drainage characteristics based on the SSURGO database at 30 m.
