Glossary
Electromagnetic Energy. Energy that is reflected or emitted from objects in the form of electrical and magnetic waves that
can travel through space.
Electromagnetic Spectrum. All wavelengths of electromagnetic energy including x-rays, ultraviolet rays, invisible light,
infrared light, microwaves, and radio waves.
Elevation. The terrain of the land measured in feet above sea level.
End-of-Pass Delay. A delay that allows any grain that passes by a yield monitor flow sensor after the combine header has
been raised to be included in calculations.
Enhanced Thematic Mapper (ETM). A device that senses multi spectral bands at a spatial resolution of 98 feet (30 m), a
shortwave thermal band at a resolution of 394 feet (120 m), multi spectral thermal bands at a resolution of 197 feet (60 m),
and a panchromatic band at a resolution of 49 feet (15 m). The ETM is scheduled to be used on LANDSAT-7.
Enhanced Vegetation Map. A map produced to accentuate the small variations in the color of the crop canopy. Two
enhanced vegetation maps cannot be compared since the scales on each map will be different.
Export Data. The process of saving data from one program (such as JDFarm Office) into a format that another program can
use. This process can create a text or graphic file.
Equipment. When we say equipment, we are referring to a John Deere combine or tractor, depending on the context of the
subject (planting or harvest).
F
Farm. In JDFarm Office, a farm is a group of fields which are located near each other. A farm may consist of one field or
multiple fields. You can have many farms defined.
Farm. Second level in storage hierarchy. Refers to a logical grouping of Fields. Data for a Client is stored indexed by Farm.
Farm names are created by the user in the desktop software.
Farm Service Agency (FSA). An agency of the U.S. Department of Agriculture. The FSA uses aerial photography for the
administration of government farm programs.
Federal Communications Commission (FCC). The government agency that is responsible for enforcing communication
standards and frequency band usage.
Field. A field is an area of land which is physically delineated by roads, creeks, railroad tracks, etc. These field names are
defined in the Setup section of JDFarm Office.
Field. Third level in the storage hierarchy. A Field represents a physical plot of land. Data for a Farm is stored indexed by
Field. Field names are created by the user in the desktop software.
Field Area. The Area is the number of acres that are legally listed on the government land registration documents. This area
will usually be larger than the area which will print on the maps and reports because it is the area of the entire plot of land -
not just the tillable portion.
Field Operations. Within JDFarm Office it is an all-inclusive term referring to either planting or harvesting.
File Folder. Options at the top of some of the input windows appear as file folder tabs.
Firmware. A computer program that drives the functionality of some electronic component.
Flag. A marker used to track and analyze conditions or variables within fields. Flags are viewed on point maps and are used
to compare yield in a flagged area to yield in the rest of the field where that condition does not exist.
Flow Sensor. A sensor that measures the amount of material traveling through a plane per unit of time.
FM Tower Correction Signal. Differential correction signal transmitted from a local tower of known location with a range of
30-40 miles. One of three common types of differential correction.
Frequency Modulation (FM). A method of transmitting information on radio waves by encoding the information as a change
in frequency or number of cycles per second.
Frequency of Coverage. A measure of how often a sensing system, such as a satellite, can be available to collect data
form a particular site on the ground.

.gsb. This is the file extension for (G)reen(S)tar (B)oundary files. This file stores a polygon (corner points) of either a closed
boundary line or a set of drain tile lines, depending on shape type and feature type.
.gsd. This is the file extension for (G)reen(S)tar (D)ocumentation data log files.
.gsy. This is the file extension for (G)reen(S)tar (Y)ield mapping data log files. GSY is generated by combines only. With
