DAO 2007-29 mandates the use of which coordinate system for all land surveys?

The main idea is that land surveys in the Philippines are anchored to a single national reference frame to ensure consistency and comparability of boundaries across the country. DAO 2007-29 requires use of the Philippine Reference System 1992 (PRS92) for all land surveys. PRS92 provides a geodetic framework tailored to the Philippines, realized in meters, so coordinates from any survey can be reliably related to one another and to national cadastral data. This standardization simplifies title descriptions, boundary adjudications, and data sharing among agencies. WGS, UTM, and a general Geographic Coordinate System are different concepts (global standard, a projection, and a latitude/longitude framework, respectively) and are not the mandated national system in this DAO. PRS92 is the specific system established for uniformity in the Philippines.
