When was the Executive Order establishing the Philippine Reference System of 1992 (PRS92) officially signed?

• A. January 5, 1992
• B. January 6, 1993
• C. January 5, 1993
• D. December 31, 1992

Answer: (C)

PRS92 was created to standardize coordinates nationwide, so the signing date of the executive order formalizes when that new national datum took effect. The official record shows the Executive Order establishing PRS92 was signed on January 5, 1993. This date marks when agencies began applying the new reference system for mapping and surveying, replacing the previous datum. The other dates don’t fit because they do not match the documented signing date.
