CONUS Field Boundaries 2010

An automated computational methodology to extract cropland fields from WELD-processed Landsat 5 TM and Landsat 7 ETM+ time series was developed. In 2010, for all the CONUS, a total of 4,182,777 fields were extracted with mean and median field sizes of 0.193 km2 and 0.278 km,2 respectively. The results were validated by comparison with field boundaries manually digitized from Landsat 5 and Google Earth high-resolution imagery.
