The main idea is that official geodetic reference data for the Philippines are published by the country’s mapping authority. NAMRIA, the National Mapping and Resource Information Authority, is responsible for maintaining and disseminating the PRS92 geodetic framework, including the First Order and Second Order Geodetic Control Points. These points are published in both print and digital formats so surveyors can access precise coordinates and network relationships needed for accurate mapping and surveying. The other agencies listed don’t handle this publication role—DENR is the parent department, while the Lands Management Service and the GSD/RSD are involved in different functions. So NAMRIA is the correct source for these geodetic control points.
