JDOffice 1.2
Client. Highest level in storage hierarchy. Refers to someone who needs to document operations on one or more Farms.
Client names are created by the user in the desktop software.
Clipboard. A temporary, invisible storage area for cut or copied text or graphics. You can paste the contents of the clipboard
into another screen. The clipboard holds the information until you cut or copy another selection.
Coarse Acquisition (C/A) Code. A unique code for each GPS satellite. The standard code used by civilian receivers.
CG Beacon Correction Signal. Differential correction signal used by the United States Coast Guard for navigation. The
signal is transmitted from a network of towers lining major U.S. water routes. One of three common types of differential
correction.
Collect-and-Weigh. A method for determining crop yield, typically on a whole field basis. Each truckload or wagonload of
grain is weighed as it leaves the field and the moisture content is determined by sampling the load.
Combine. When we say combine, we are referring to a John Deere combine harvesting your crop.
Combine Dynamics. Parameters that can be adjusted to reflect the delay incurred in delivering grain from the feeder house
to the top of the clean grain elevator. There are also parameters for adjusting how much data is retained during the transition
from Run to Hold, and Hold to Run.
Contour. A method of interpolation originally used to display elevation changes on a topographic map. Contour lines are
lines connecting points of equal elevation of yield.
Contour Line. A line, or set of points, representing the same value of an attribute. Commonly used for illustrating lines of
the same elevation on a topographic map.
Contour Map. A color map which averages the raw field data and displays the results as a solid area, showing trends in
yield or moisture variation within the field in varying colors. The coloring of the field trends is done by using the usercontrolled
legends. The shape of the contour field is dependent on the field boundary.
Control Segment. The portion of GPS consisting of a network of monitoring stations used to update satellite navigation
signals.
Controller. An electronic device used to change product application rates on-the-go.
Crop Scouting. Visual assessment of crop condition including growth stage/maturity, plant vigor, presence of disease,
weed infestation, and insect infestation.
Crop Weight. The standard dry measure for the selected crop. Used in conjunction with standard payable moisture, these
numbers are used to calculate the average dry yields and total dry yields. Crop weight is independent of variety type.
Cut. Removing selected text or graphics from the file and placing it on the clipboard for future use.
D
Database. A collection of files managed as a unit. A GIS database includes data about the position and the attributes of
geographic features.
Data Standardization. The process of achieving agreement on the recognition of common data definitions, representation,
and structure.
Dead Reckoning. A method for calculating field position based on vehicle velocity, equipment width, travel time, and
number of passes through a field. Errors in position can be caused by speed changes, wheel slippage, nonparallel or
overlapping passes, and starting and stopping at the ends of the field.
Department of Defense (DOD). The organization responsible for the creation and operation of the Global Positioning
System.
Desktop Software. A computer program typically used on a personal computer.
Dielectric. A material that can sustain an electric field but does not conduct electric current.
Differential Correction. Correction of a GPS signal to improve its accuracy. The correction is performed using a second
stationary GPS receiver positioned at a known location. This receiver computes the error in the signal by comparing the true
distance from the satellites to the GPS measured distance. Three common types of differential correction are Coast Guard
Beacon Correction Signal, FM Tower Correction Signal, and Satellite Solution.
Differential Global Positioning System. A method of using GPS that improves the position accuracy through differential
correction.
E
Electro-Optical Sensor. Light-sensitive, electronic detector that create an electrical signal proportional to the amount of
electromagnetic energy that hits it.
