The Triangulation Station Balanacan, located in Marinduque, is associated with which datum?

• A. PPCS/Luzon1911
• B. Luzon 1911 Datum
• C. PRS92
• D. Local Plane Datum

Answer: (B)

The key idea here is that a triangulation station’s coordinates are defined relative to a geodetic datum, which is the reference surface and frame used for measuring positions. In the Philippines, the historical national triangulation network was anchored to the Luzon 1911 Datum. Triangulation Station Balanacan, located in Marinduque, is part of that old network, so its coordinates are tied to the Luzon 1911 Datum. The Philippine Plane Coordinate System is a projection derived from that datum to give grid coordinates, not the datum itself. PRS92 is a more modern datum, and Local Plane Datum isn’t an official standard in this context.
