Which term refers to the Philippine Reference System of 1992, a national common coordinate reference system for all surveys and maps pursuant to Executive Order No. 45 dated January 5, 1993, as amended?

PRS91

Philippine Spatial Reference

National Coordinate System 1993

PRS92

The main idea here is recognizing the official national coordinate reference framework adopted for all surveys and maps in the Philippines. The Philippine Reference System of 1992 is the standard designation for this framework, abbreviated as PRS92, which was established by Executive Order No. 45 in 1993 (as amended). This system provides a single, nationwide geodetic reference so that maps and survey data from different sources can align consistently. PRS91 refers to the older system, which is not the current official term, while the other options do not match the formal designation used in Philippine surveying and mapping. Therefore, the correct term is PRS92.
