          TACLOBAN CITY  – 
           Secretary Ramon Paje of the Department of Environment and Natural 
          Resources (DENR) issued a mandate to all DENR offices in the country 
          to adopt the Philippine Reference System of 1992 (PRS 92) in all 
          surveying and mapping activities of the DENR.
          
          PRS 92 is a 
          homogeneous network of geodetic control points, marked by survey 
          monuments or mojons, established using the Global Positioning System.  
          It was established in 1989-1992 through an Australian assisted project 
          of the DENR.  PRS 92 upgraded the old national geodetic network called 
          Philippine Geodetic Network established by the United States Coast and 
          Geodetic Survey in 1901 to 1946.
          
          Pursuant to the 
          mandates of the previous Presidents of the Philippines through 
          Executive Order No. 45 series of 1993, as amended by EO 280 series of 
          2000 and E.O. No. 321 series of 2004, the PRS 92 became the standard 
          reference system for all surveys and mapping activities in the 
          country.
          
          Effective January 
          2011, Secretary Paje ordered that all surveys, maps and plans being 
          undertaken by the DENR from the Central down to its field offices, 
          shall be compliant with PRS 92 as requirement for its approval.
          
          Regional Executive 
          Director Primitivo C. Galinato, Jr. disclosed that said order of 
          Secretary Paje is a great help in land disposition and management.  
          “By adopting the PRS 92 system in all surveys and mapping activities 
          of the DENR, it will solve the problem of creating apparent overlaps 
          and gaps between adjoining parcels of land.  This will also 
          standardize the mapping system in the country so that a particular 
          point or space on the ground will have only one location in any 
          official Philippine map.  I just wish that succeeding mandates shall 
          be given to other mapping and surveying agencies like the Departments 
          of Agrarian Reform, Public Works and Highways, Agriculture, National 
          Irrigation Administration, among others, so that we can harmonize all 
          our convergence activities”, Galinato quipped.
          
          Regional Technical 
          Director Ramon S. Unay of the Land Management Service of the DENR 
          disclosed that the Land Management Service through its Field Network 
          Survey Party is currently establishing Geodetic Control Points or 
          “mojons” under the PRS 92 program.  “These mojons are being 
          established in the barangays and towns all over the region.  These 
          mojons serve as the standard reference points for all surveying and 
          mapping activities.  Since these are all established in the barangays 
          and towns, we call on the cooperation of the local government units, 
          who are adopters of these mojons, to help the DENR in advocating the 
          significance of these mojons and enjoin their respective constituents 
          to protect and help preserve these mojons so that it can serve its 
          purpose”, RTD Unay remarked.
          
          These mojons have 
          indirect impact to the constituents. Together with other components of 
          PRS 92, successful implementation of the program help  to complete and 
          maintain the national geodetic network and integrate old surveys and 
          maps into the network for the sustainable management and development 
          of the country’s natural resources and to establish more accurate 
          spatial positioning for infrastructure and other activities.  
          Generally, this will facilitate the implementation of poverty 
          alleviation, economic development, as well as climate change 
          mitigation programs of the government.
