Pagadian City - The Department of Environment and Natural Resources (DENR) Regional Office IX is now intensifying the implementation of the so-called Philippine Reference System (PRS) of 1992 primarily aimed to provide better user access to geodetic network information.
Under this program, DENR plans to upgrade the current geodetic control database into a web-based Geodetic Network Information System (GNIS) that will eventually have both central and regional operations. The establishment of continuously operating reference stations, generally known as Active Geodetic Stations (AGS) is also being envisioned to expedite the densification work and provide real time positioning services to users communities.
PRS92 is a homogenous national network of geodetic control points (GCPs), marked by survey monuments or mojons, that have been established using the Global Positioning System (GPS) technology. GPS is an all-weather, high precision, global satellite positioning system that revolutionized navigation and surveying operations.
By virtue of EO 45, PRS92 became the standard reference system for all surveying and mapping activities in the Philippines.
PRS92 was first implemented through EO 45 under the administration of former President Fidel Ramos. Subsequently, it was amended by EO 280 extending its full implementation by 2005. In order to complete the adoption and integration of the old surveys into a system until 2010, EO 321 was issued by President Gloria Macapagal-Arroyo.
Under EO 321, the National Mapping Research and Information Authority (NAMRIA), Lands Management Bureau and the DENR Regional Operations Committees are tasked to primarily execute the order. DENR Regional Executive Director Maximo Dichoso through the Regional Public Affairs Office (RPAO) are now conducting information education campaign throughout the region and to come up with a Memorandum of Agreement (MOA) between the Local Government Units (LGUs) and DENR.
The network or system is extensive wherein an average of three (3) geodetic control points (GCPs) shall be installed in every barangay with an interval of five (5) kilometers from each point. With about 42,000 barangays in the whole country, the total requirements of GCPs will sum up to approximately 126,000. With this, all adjusted old maps and surveys are also integrated into the new network.
According to Mr. Roservirico "Obing" Tan, RPAO Officer in Charge, as of the moment there are 24 local government units (1 City and 23 Municipalities) in the region who have signed the agreement with DENR since 2007. (PIA RO9)
