The modified Luzon Datum 1911 was adopted as the datum for which coordinate system?

Explanation:
A geodetic datum defines the reference frame that positions are measured from. The Modified Luzon Datum 1911 (MLD1911) was adopted as the datum for the Philippine Reference System 1992 (PRS92), making PRS92 the nationwide plane coordinate system anchored to MLD1911. This pairing was chosen to improve consistency with ground surveys and GNSS data across the Philippines while staying compatible with older data. It’s not the basis for a purely local plane system or for the Luzon1911-based or PRS92-projected variants alone, so the nationwide system tied to MLD1911 is PRS92.
