Abstract
A field mapping system for an agricultural vehicle such as a combine, planter or cultivator is disclosed herein. The system includes a circuit for determining the position of the vehicle relative to a field, and a sensor for sensing a characteristic (e.g., grain moisture content, grain harvest yield, soil compaction, altitude, etc.) at locations of the vehicle within the field. The system also includes an electronic display controlled by a control circuit coupled to the position determining circuit and the sensor. The control circuit applies signals to the electronic display which produces a map of the field including indicia of the characteristic at respective locations within the field. (For example, if the characteristic is grain moisture content, different colors can be used on the display to represent different moisture levels.) The signals are generated by the control circuit so that the portion of the field over which the characteristic is sampled is scaled to be displayed over substantially all of a portion of the display. Thus, as the area of the field which has been sampled increases, the scale of the displayed map is automatically rescaled to show all of the data.
