Are there any disadvantages to using a coordinate grid to describe location?
Disadvantages of a projected coordinate system on the Cartesian plane—Almost every point is in the wrong place, although maybe not by much. All projections introduce errors. Depending on the projection, these errors are in distances, sizes, shapes, or directions.
What is the importance of geographic coordinate system?
A geographic coordinate system enable geographic data to use common locations of geographic features, imagery, and observation within a common geographic framework. Many of us use this coordinate system in what is called Global Positioning Systems (GPS) locations.
Why are coordinates stored in a geographic coordinate system?
If you store the coordinates in a projected coordinate system, these things are calculated in a Euclidean way, which means there will be huge distortions if your map covers a larger area of the earth. So, in my view, storing the coordinates in a geographic coordinate system has the

What are the advantages of a spherical coordinate system?
Advantages of the spherical coordinate system—You can represent any point on the Earth’s surface as accurately as your measurement techniques allow. The system itself does not introduce errors.
What do you mean by arbitrary coordinate system?
All coordinate systems are arbitrary. By a coordinate system, we simply mean an alphanumeric system by which the positions of geographic objects can be be unambiguously described. By arbitrary, we mean there’s no magic to how these systems were developed…they are completely contrived.
