FALSE NORTHING Meaning and
Definition
-
False northing is a term used in cartography and coordinate systems to describe an artificial displacement of the origin of a north-south coordinate axis to a predetermined value. This displacement is added to the true geographic coordinates in order to avoid the use of negative numbers and facilitate calculations.
In geographical coordinate systems, such as latitude and longitude, the origin is typically set at the intersection of the equator and a chosen meridian. However, in some cases, a false northing is introduced to shift the origin to a desired location further north. This displacement is typically measured in units of length, such as meters or feet.
The purpose of a false northing is to simplify the numerical representation of geographic data and make calculations more intuitive. By avoiding negative numbers, it improves map readability and presentation. Additionally, it eliminates the possibility of confusing a negative northern coordinate value with a southern coordinate.
False northing values are chosen based on the specific requirements of the coordinate system or map projection being used. These values can vary depending on the region and scale of the map. It is important to note that false northing affects the y-coordinate or the northing coordinate, while the x-coordinate or the easting coordinate remains unaffected.

Etymology of FALSE NORTHING
The term "false northing" is primarily used in the field of cartography and map projection. Etymologically, it originates from combining two words: "false" and "northing".
- "False" comes from the Middle English word "fals", which means "deceptive" or "untrue". It can be traced back to the Old English word "fǣls", meaning "fraudulent" or "unfaithful".
- "Northing" refers to a northward movement or distance measured in the north-south direction. It is derived from the verb "north", which means to move or travel towards the north. The word "north" can be traced to the Old English word "norþ", meaning "north" or "northern region".
