The mathematical system of locating positions based on the standard datum and PGC is known as which term?

When locating positions in surveying, the framework that ties every point to numbers using a defined reference and a grid is a coordinate system. A datum provides the reference shape and origin of the Earth, while the projection (the PGC aspect) converts those positions onto a flat grid so coordinates can be expressed as x and y. Put together, they form the coordinate system—the standard way to locate any point with numerical coordinates. Local Plane Coordinate System is a type of coordinate system focused on a small area, but the question asks for the general term. Luzon Datum 1911 is a datum by itself, not the whole system. A reference point is simply a known point used as a basis, not the system used to locate positions.
