EQUIVALENT PROJECTIONS Meaning and
Definition
-
Equivalent projections refer to a term commonly used in mathematics and cartography to describe two or more different map projections that can represent the same geographic area accurately. A map projection is a method of depicting the curved surface of the Earth onto a flat surface, like a piece of paper or a computer screen. However, since the Earth is a three-dimensional object and maps are two-dimensional representations, distortions inevitably occur when trying to project the entire surface of the globe onto a flat surface.
When two or more map projections are considered equivalent, it means that they retain the same basic properties and accurately represent the spatial relationship between points on the Earth's surface. These projections generally have similar shapes, angles, and distances relative to each other, making them useful for comparing and analyzing geographic information.
One common example of equivalent projections is the Mercator projection and the Robinson projection, both of which aim to preserve accurate shapes and directions while sacrificing some accuracy in scale and distance. These projections are used in various applications, such as navigation charts, because they provide a useful representation of the world with minimal distortions.
In summary, equivalent projections are a set of map projections that share similar characteristics and accurately represent the relationships between points on the Earth's surface. They are essential in cartography to ensure that maps can be compared and analyzed effectively, despite the necessary distortions incurred in projecting a three-dimensional object onto a two-dimensional surface.

Etymology of EQUIVALENT PROJECTIONS
The word "equivalent" traces its origins to the Latin word "aequivalens", which is the present participle of "aequivalere", meaning "to be equal". "Aequi" means "equal", and "valere" means "to be strong" or "to have worth".
The term "projection" comes from the Latin word "projectio", which stems from "proiectus", the past participle of "proicere". "Pro" means "forward" or "forth", and "iacere" means "to throw".
Combining these two words, "equivalent projections" refers to producing images or representations that are equal or have the same value, whether visually or in some other context.
