Verification of AgTile-US tile drainage data with 16000 ground truth points. (a) Distribution of 16000 tile drainage ground-truth points on drainage category-topographic slope two-dimensional distribution space, (b) As in (a), but for AgTile-US tile drainage data, (c) As in (b), but for ‘false’ AgTile-US grids when compared to ground truths (False-True), (d) As in (b), but for valid or ‘true’ AgTile-US (True-True), In (a–d), turquoise color grading over the box and whisker plot and number in turquoise color over the panel (a,b) indicate the data density in each drainage category and colored ellipse indicate the data distribution density (%), (e) AgTile-US accuracy distribution on drainage category-topographic slope two-dimensional distribution space based on ground truth points, In (e), black line indicates isoline of accuracy or accuracy contour, (f) State-wise summary of accuracy assessment for selected nine states. In (f), N indicates the total number of ground truth identified. In (ae) x-axis indicate soil drainage categories, 1-Excessively drained, 2-Somewhat excessively drained, 3-Well drained, 4-Moderately well-drained, 5-Somewhat poorly drained, 6-Poorly drained, and 7-Very poorly drained.
