What is World Coordinate System?

The World Coordinate System (WCS) is a standard for representing scalar field data in three dimensions. It is commonly used in computer graphics, scientific visualization, and astronomy.

WCS is an important tool for visualizing data in three dimensions. By using WCS, astronomers can map the positions of objects onto a two-dimensional plane. This allows them to visualize the distribution of objects in space and to study their relationships with one another. Additionally, WCS can be used to create three-dimensional models of astronomical objects, which can be useful for educational purposes or for planning observations.
