A coordinate system is a method for identifying the location of a point on the earth. Most coordinate systems use two numbers, a coordinate, to identify the location of a point. Each of these numbers indicates the distance between the point and some fixed reference point, called the origin.
Here's more about the coordinate system
A coordinate system is a framework that allows us to locate and describe points in space. It consists of a set of axes, which are imaginary lines that intersect at a point called the origin. The axes are typically labeled with letters x, y, and z, and are used to define the coordinates of a point. Coordinates are values that indicate the position of a point along each axis. In a 2-D coordinate system, coordinates are given as (x, y), while in a 3D coordinate system, they are given as (x, y, z). This helps in plotting and analyzing data.
