Precision Agriculture
Glossary
A
A-B LINE. The imaginary reference line set for each field that a tractor/sprayer guidance system to follow. There are different reference lines that can be set in a field to fit a particular geography or layout.
AGRONOMIC DATA. Represents data compiled from a specific farming operation or at the field level generally related to agronomy-based information such as yield, population, hybrid, and nutrient application.
ALGORITHM. A set of steps or rules for making calculations or solving problems, as used in computer programs.
ARTIFICIAL INTELLIGENCE. Artificial intelligence (AI) is a field of computer science that focuses on building smart machines capable of performing tasks that otherwise require human intelligence. This field looks at ways to program machines to analyze and interpret data for decisions such as watering or chemical applications.
AUTONOMOUS OPERATION. Vehicle guidance without the need for human intervention. A tractor may be driven by a series of onboard sensors and GPS for precision driving without damage to crops.
AUTO SECTION CONTROL. A system that operates boom sections automatically using a positioning system and precise on-off timing to minimize over-application caused by overlapping or missed areas caused by underlapping. ASC can be used on self-propelled, trailed, or mounted sprayers.
AUTO-STEER. A GPS guidance system that steers agricultural equipment with centimeter accuracy. This level of accuracy requires real-time kinematic (RTK) correction of GPS signals. Auto-steer is an add-on component for equipment. It includes both the GPS system to receive and process the signals, software, and hardware to allow the input of control maps, and the mechanical equipment to actually steer the tractor. Some new tractors are available “auto-steer ready.”
