Description:
This is a geoid model for Philippines computed by the National Mapping and Resource Information Authority (NAMRIA). The geoid covers the region 4-22°N, 112-128°E, and has a resolution of 0.025°. It is an update of the previous PGM2016 model, using new satellite gravity and altimetry data and densified land gravity data. The same procedure of PGM2014 and PGM2016 was used i n the computation of the PGM2018 model. The resulting gravimetric model was fitted to ITRF2005 GNSS/levelling benchmarks. The PGM2018 model has an estimated accuracy of 1.2 cm.
