Which coordinate system is mandated by DAO 2007-29 to ensure consistency across surveys?

Explanation:
DAO 2007-29 requires the Philippine Reference System 1992 (PRS92) as the official geodetic reference for all surveys. This gives every survey a single, consistent frame of reference, so coordinates, elevations, and results can be compared and combined reliably across regions and projects. While global systems like WGS84 or projection methods such as UTM may be used in fieldwork or mapping, PRS92 is the mandated standard for ensuring uniformity and legal compatibility in Philippine surveying. PRS92 is tied to the national control network and designed to minimize discrepancies that come from using different datums, making sure that the country’s surveys align with one another.
