Official PRS92 Transformation Parameters
For GPS users, the following transformation parameters will be necessary when undertaking local surveys. They relate the WGS84 Datum, to which all GPS data is referenced to PRS92 on the Luzon Datum. These parameters are applied to WGS84 geocentric cartesian coordinates to give cartesian coordinates of the PRS92 datum which will then be transformed to geographical PRS92 coordinates.
Transformation parameters (WGS84 to PRS92):
Delta X = 127.62153 meters
Transformation parameters (PRS92 to WGS84):
Delta X = -127.622 meters
The general similarity transformation formula that relates two sets of coordinates is shown below:
A workshop on the establishment of the NAMRIA spatial data infrastructure (nSDI) was held at the NAMRIA Lecture Hall last 18 August with participants from the agency’s various departments, most of whom attended the Strengthening NAMRIA Middle-Management Leadership training. The workshop was spearheaded by the ad hoc technical working groups (TWGs) on institutional framework, fundamental datasets and standards, and clearinghouse network.
The Interagency Task Group Balanacan spearheaded by Deputy Administrator Linda SD. Papa presented the Station Balanacan preservation initiatives to the Marinduque Provincial Government on 16 August 2010. The interagency task group is composed of representatives from NAMRIA and the Region IV-B office of DENR. The group works with local government units, regional line agencies, and the National Historical Commission of the Philippines (NHCP) in carrying out its initiatives.
NAMRIA hosted the PRS92 Program Review and Analysis (PRA) for Luzon on 07-08 April 2010 and for Visayas and Mindanao on 22-23 April 2010 at the NAMRIA Lecture Hall in Fort Bonifacio, Taguig City.

What is PRS92?
PRS92 or the Philippine Reference System of 1992 is a homogeneous national network of geodetic control points (GCPs), marked by concrete monuments or mojons, that has been established using Global Positioning System (GPS) technology.
