The model criteria incorporated publically available data including agricultural land use data identified by the National Land Cover Dataset (NLCD) and the National Agricultural Statistics Service (NASS), soil characteristics obtained through the Soil Survey Geographic Database (SSURGO), and slope characteristics developed from the National Elevation Dataset (NED). Results indicate that with the best combination of criteria the model predictions correspond nearly 80% with the actual drain tile data. The potential to incorporate the influence of drain tile areas into land-use based assessments of wetland and waterway health is an important outcome of being able to identify land drained by artificial subsurface drainage features.
