X Coordinate (Abscissa)
The horizontal value in a pair of coordinates (x, y) that specifies a location in two-dimensional space. In GIS, x typically represents longitude (east-west position) or the easting value in projected coordinate systems.

What is the X Coordinate (Abscissa) used for?
The horizontal position of a point in a two-dimensional coordinate system, like a map or spatial grid, is represented by the X coordinate, also called the abscissa. The X coordinate is commonly used in GIS and mapping applications to measure the east-west distance from a specified origin point (0,0). It functions in tandem with the Y coordinate (ordinate), which denotes the north-south position, and is a crucial component of geographic coordinate systems. When combined, these coordinates provide the precise location of points, lines, and polygons on the surface of the Earth. In digital mapping, data plotting, and geographical analysis, the X coordinate is particularly crucial since it enables users to precisely identify and view features on a map. The X coordinate is essential for making sure that geographical data is correctly aligned and processed, regardless of whether geographic coordinate systems (such as latitude and longitude) or projected coordinate systems (such as UTM) are being used.

In geometry, the x-axis is the horizontal line in a coordinate plane that is used to plot points, shapes, and graphs. It runs left to right and is usually paired with the vertical y-axis to form the Cartesian coordinate system. Points on the x-axis have coordinates in the form (x, 0).
The x-coordinate in the Cartesian coordinate system is a horizontal coordinate in mathematics. It indicates a point's distance from the vertical y-axis by traveling along the horizontal axis to the left (negative) or right (positive).
The horizontal location of a point in a Cartesian plane is represented by the X-coordinate, often known as the abscissa. It displays the point's distance from the origin (0,0) to the left or right. On the right are positive X-values, and on the left are negative X-values.
The horizontal coordinate (x-coordinate) of a point in a Cartesian plane is known as the abscissa in mathematics. It shows the point's distance, measured along the x-axis, from the vertical y-axis. For instance, the abscissa in point (3,5) is 3.
