Projection refers to the description of the manner in which the coordinates are represented on a 2D plane. Projections represent the way the Earth is "reported" when you turn a 3D object into a flat 2D representation.
Map projections have been defined into some common forms which describe the shape of the plane as well as the distance measurements. Examples of these include:
1. Surface projection types
- Cylindrical
- Conical
- Azimuthal (projections onto a plane)
2. Metric descriptions
- Conformal
- Equal-area
- Equidistant
