Geomorphological forms maps and confusion matrices. The geomorphological forms have been computed for a study area of 3000 × 3000, 100 m pixels in South Dakota (USA) derived from MERIT (a–c) and 3DEP-1 (b–d), respectively. The confusion matrix values are expressed in percentages of the MERIT-DEM classes, with the sum of vertical values equal to 100 (d); and of the 3DEP-1 classes, with the sum of the horizontal values equal to 100 (c). The sum of the values in the blue boxes is equal to 100, and so on for each row (c) and column (d).
