Users can control the colors to highlight the material they wish to remove.
In the screen to the right, the red material is less than the channel design depth. This color-coded depth display is remapped as the cutting tool passes through each cell at a depth lower than the depth value. This allows the operator to increase their digging efficiency by working in precise areas where material is available. For a cutter suction dredge, this is a profile along the radius of the digging tool. For hopper dredges, this can be longitudinal or transverse profiles through the drag arm heads.
