Figure 5. Differential map of the study area. The colder colors indicate where the surface produced by contouring the points using each method differs from each other. Blue areas indicate where the handpicked surface is lower in elevation than the auto-picked method, red areas indicate the hand-picked surface is higher in elevation than the auto-picked method; Green areas indicate where the surfaces are roughly equal in elevation.
