Answer:
Georeference
Step-by-step explanation:
All farmers know their fields, but numbers and data that can be tied to GPS data and keyed into a system is much more effective than relying on memory. Reports of grid soil samples, soil maps, aerial photographs, yield maps, and soil texture maps that are linked to GPS coordinates (i.e., georeference) are the foundation of precision agriculture. Often, these techniques reveal patterns of which the farmer was unaware.
