Abstract

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 produces display signals applied to the electronic display to generate a map of an area of the field at a desired scale which includes indicia of the current vehicle location and of the characteristic data being gathered. The map is dynamically redrawn at the desired scale to keep the visual indicia displayed when the vehicle has moved such that the vehicle location no longer corresponds to the displayed area.
