GRID REFERENCE Meaning and
Definition
-
Grid reference is a term used in cartography and navigation to indicate a specific location on a map or grid system. It is a method of determining the coordinates of a point on a two-dimensional surface or map, often consisting of a horizontal grid of numbered lines intersecting with a vertical grid of numbered lines. These horizontal and vertical lines form a grid network, with each line representing an increment on the X or Y axis.
In a typical grid reference system, the horizontal lines are called eastings, while the vertical lines are called northings. The point of intersection between a specific easting and northing represents a unique coordinate, allowing for precise location identification.
Grid references are commonly used in various fields such as geography, surveying, and outdoor activities like hiking and orienteering. To determine a grid reference, one must identify the numbered lines that intersect closest to the desired location and note down the corresponding easting and northing values.
The accuracy of a grid reference is determined by the spacing between the grid lines, usually measured in units such as meters or miles. The precise grid reference is typically expressed as a set of numbers or alphanumeric characters representing the easting and northing values, respectively.
Overall, grid references provide a systematic and accurate method of pinpointing specific locations on a map, facilitating effective navigation and communication.

Etymology of GRID REFERENCE
The word "grid reference" is a compound noun composed of "grid" and "reference".
"Grid" originates from the Middle English word "grit", which referred to a network of lines forming squares. It has its roots in the Old English word "grytte", meaning a rectangular framework. The term also comes from the Old Norse word "grind", which meant a gridiron or a grate.
"Reference" is derived from the Latin word "referentia", meaning the act of referring something to someone or something. It is composed of "re-" (meaning back or again) and "ferentia" (from "ferre", meaning to carry or bring).
Therefore, the etymology of the word "grid reference" implies the act of using a square network of lines as a point of referral or indication in a system or a map.
