Panning display of GPS field maps
First Claim
1. A system configured to sample at least one site-specific characteristic of an agricultural field at a plurality of locations within the field, comprising:
- a vehicle moveable over the field;
a location signal generation circuit supported by the vehicle to generate location signals representative of the plurality of locations within the field;
a sensing circuit supported by the vehicle to generate characteristic signals representative of a characteristic sampled at the plurality of locations within the field;
a control circuit coupled to the generation circuit and the sensing circuit, the control circuit configured to correlate location data representative of the location signals generated at the plurality of locations with characteristic data representative of the characteristic signals generated at the respective plurality of locations; and
an electronic display supported by the vehicle and coupled to the control circuit, the electronic display including a map display area, the control circuit configured to produce a display signal which, when applied to the electronic display, generates a map at a desired scale within the map display area which includes visual indicia of the characteristic data which corresponds to the map display area, the indicia of the characteristic data including a plurality of data blocks and, when the location of a newly generated data block no longer corresponds to the map display area, dynamically redraws the map at the desired scale within the map display area to include the newly generated data block.

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.
