Description:
The PNG94 model is a gravimetric geoid for Papua New Guinea. The computation is based on the remove-restore technique using 34,163 free air gravity data provided by GETECH, a commercial arm of the Department of Earth Sciences at Leeds university, UK. The reference global model is OSU91A, while no terrain corrections are computed because no DTM is available. A ring integration technique is used to compute the final geoid grid with a spatial resolution of 0.1°.
