Abstract: A method for developing a landfill with a compactor machine having a three-dimensional position sensing equipment, a computer, and a display. The method includes traversing the worksite with the compactor machine and determining deflection of the worksite at a plurality of locations while each of the locations is beneath the compactor machine. The compactor machine defines wheel tracks over which a plurality of wheels pass while traversing the worksite. The method includes recording the determined deflection of each of the locations on the display. The deflection may be recorded beneath only the wheel tracks of the compactor machine, such that areas passing between the wheel tracks of the compactor machine are not recorded on the display.
