The Triangulation Station Balanacan uses which datum?

A geodetic datum defines the reference frame for coordinates, including the origin and the ellipsoid used. In the Philippines, many older triangulation networks were established using Luzon Datum 1911. Triangulation Station Balanacan falls within that traditional network, so its coordinates are tied to Luzon Datum 1911. Modern systems like the Philippine Reference System of 1992 (PRS92) are tied to newer frames (WGS84), World Geodetic System 1984 is a global standard, and the Philippine Geoid Model is used for converting between ellipsoidal and orthometric heights rather than as a coordinate datum. Therefore, the datum used for Balanacan is Luzon Datum 1911.
