Abstract
A field mapping system for an agricultural vehicle such as a combine or tractor is disclosed herein. The system includes a location signal generator for determining the position of the vehicle relative to a field, a correction signal generator for receiving correction signals used to improve the accuracy of the position determination and a sensing circuit for detecting a characteristic (e.g., grain moisture, grain flow, soil compaction, soil moisture) at predetermined locations of the vehicle within the field. The system also includes an electronic display controlled by a control circuit coupled to the location signal generator, the correction signal generator, and the sensing circuit. The control circuit applies signals to the electronic display which produces a map of the field which includes indicia of the characteristic at respective locations within the field. For example, if the characteristic is grain moisture, different colors can be used on the display to represent different moisture levels.
