  5. A geographic coordinate system (GCS) uses a three-dimensional spherical surface to define locations on the earth. A GCS is often incorrectly called a datum, but a datum is only one part of a GCS. A GCS includes an angular unit of measure, a prime meridian, and a datum (based on a spheroid ). A point is referenced by its longitude and latitude ...

    The prototypical example of a coordinate system is the Cartesian coordinate system, which describes the position of a point P in the Euclidean space Rnby an n-tuple 1. P = (r1, ..., rn) of real numbers 1. r1, ..., rn. These numbers r1, ..., rn are called the coordinates linear polynomials of the point P. If a subset S of a Euclidean space is mapped...

    A coordinate transformationis a conversion from one system to another, to describe the same space. With every bijection from the space to itself two coordinate transformations can be associated: 1. such that the new coordinates of the image of each point are the same as the old coordinates of the original point (the formulas for the mapping are the...

    Some coordinate systems are the following: 1. The Cartesian coordinate system(also called the "rectangular coordinate system"), which, for three-dimensional flat space, uses three numbers representing distances. The three numbers represent first: the East or West direction, second: the North or South direction, and third: the Elevation. 2. Curvilin...

    A geographic coordinate system (GCS) defines locations on the earth using a three-dimensional spherical surface , it is a reference system that uses latitude and longitude to identify locations on a spheroid or sphere. Oftentimes GCS are referred to solely as datums however, a datum is just one part of a GCS. A GCS includes a datum (based on a sphe...

    Rather than using degrees to represent points on a spheroid, some coordinate systems are placed on 2-dimensional projections and function much like the previously mentioned Cartesian System. These coordinate systems often use measurements in feet or meters to express x and y coordinates for specific points. The advantages of these systems are in th...
