A second data processor determines candidate passes of the second vehicle in alignment with the defined plant rows to provide area coverage of the work area or field within the defined boundary based on an implement width or swath of the second vehicle and row spacing of the second vehicle, wherein the one or more candidate passes are associated with the defined plant rows consistent with a planned guidance path. From the present position and heading of the second vehicle, a user interface or display displays the determined candidate passes to minimize overlap of adjacent candidate passes of the second vehicle and to minimize any yield loss associated with unharvested/untreated passes or zones within the work area or field. The user interface or display supports selection of one of the displayed or presented candidate passes as the planned guidance path of the second vehicle consistent with the provision of area coverage of the work area or field.
