A swathing guidance system includes a controller storing data defining a desired vehicle path, a position detector subsystem such as a differential GPS receiver, and a display to graphically display current spatial parameters and corrective steering actions to place the vehicle on the desired path or to maintain it on the path. The controller periodically selects a future intercept point on the path and calculates a steering correction angle to point the vehicle toward the intercept point. The display includes a steering guide which displays the steering correction angle relative to the current heading and the current track error or distance from the desired path. The steering correction angle can alternatively be applied to an automatic steering mechanism to automatically maintain the vehicle on the desired path. In agricultural applications, the system is applicable to both parallel and contour cultivation modes.
