OS improving mapping capability in the Philippines

Optimising GPS active network performance to enhance geospatial infrastructure

Optimising GPS active network performance to enhance geospatial infrastructure.

The National Mapping and Resource Information Authority (NAMRIA) maintains the Philippine Geodetic Reference System (PGRS) – the primary reference for all surveying and mapping in the country. Ordnance Survey (OS) supported the modernisation of its geospatial infrastructure.



In line with its modernisation plans, NAMRIA asked Ordnance Survey to optimise the performance and value of its Philippine Active Geodetic Network (PageNET), the country’s network of permanently installed and continuously operating geodetic reference stations (CORS).

This posed a number of challenges:

  • Updating CORS infrastructure and support.
  • Establishing users’ current and future needs.
  • Moving towards real-time infrastructure and associated services.
  • Optimising the performance and value of PageNET.
Field systems in the Philippines


Ordnance Survey partnered with Newcastle University and software provider Leica. The modernisation needed to account for the effects of geodynamics in PGRS.

Training was provided to give NAMRIA better insight into the effects of ground movements brought on by seismic events and tectonic plate motion.

We also ran user analysis workshops for NAMRIA to better understand the needs of PAGEnet customers, now and in the future. Sectors covered included disaster risk reduction and management, surveying and mapping, infrastructure, transportation and environment. The current PageNET system was also reviewed, to maximise potential and usage.


  • An expert understanding on how to better serve NAMRIA customers and what their users want.
  • An accurate underlying geospatial infrastructure to serve government departments.
  • A cheap, easy-to-access, and uniform system to underpin the accurate data.
  • The whole nation is now joined up, with different sectors using the same data and standards.

"We are delighted to have worked with OS. Their world class expertise has helped us review our GPS active network to ensure we are getting the best possible usage and also making it widely available for other purposes across Philippines government."
