Which term describes representing a curved surface on a plane for mapping?

Mapping a curved surface onto a plane is called a projection. This is the process cartographers and surveyors use to transfer the Earth's curved surface onto a flat map, choosing which properties to preserve (like angles or areas) while accepting distortions in others. The ellipsoid is the three-dimensional shape used as a mathematical model of the Earth, not the act of converting to a plane. A datum provides the reference framework that defines the relationship between the model and coordinates, but it’s about the reference system, not the mapping action. A coordinate system is the scheme for labeling positions once you’re already in a planar frame, not the transformation itself. So the term that describes representing a curved surface on a plane is projection.
