1. A method for estimating surface roughness of a ground for an off-road vehicle to control an implement, the method comprising:
detecting motion data of an off-road vehicle traversing a field or work site during a sampling interval, the motion data comprising ground speed of the off-road vehicle;
detecting, by a first sensor or an inertial sensor module, pitch acceleration data of the off-road vehicle for the sampling interval;
detecting, by a second sensor or the inertial sensor module, roll acceleration data of the off-road vehicle for the sampling interval;
determining, by an electronic data processor, a surface roughness index based on the detected motion data, pitch acceleration data and roll acceleration data for the sampling interval;
estimating zones with corresponding surface roughness index ranges within the field or work site based on the determined surface roughness index as the off-road vehicle traverses or traversed the field or work site over multiple sampling intervals;
generating a graphical display that illustrates the estimated zones of corresponding surface roughness or index ranges within the field or work site;
displaying, on a user interface, the generated graphical display to a user or operator of the off-road vehicle; and
estimating a downforce setting for the implement of the off-road vehicle based on the determined surface roughness index to adjust the estimated down-force setting for one or more zone thresholds of a respective surface roughness index range of the estimated zone.
