After full implementation, which datum shall be the sole datum for all surveys and mapping in the country?

Explanation:
A single, official geodetic reference frame is needed to keep all survey measurements and maps consistent across the country. In the Philippines, that official national datum is the Philippine Reference System of 1992 (PRS92). PRS92 provides a unified, geocentric framework that all surveys, cadastral work, and mapping projects align to, so coordinates from different surveys and agencies correspond exactly to one another. While WGS 84 is a global standard used with GPS data, and NAD83 is a North American datum, they are not the national reference for the Philippines. UTM is a projection method, not the reference frame itself. Therefore, PRS92 serves as the sole datum for nationwide surveys and mapping.
