Abstract
Computation of a new gravimetric geoid in Brunei was carried out using
terrestrial, airborne and altimetric gravity data and the EGM08 geopotential model by
the collocation method. The computations were carried out by the „
remove-restore
”
technique. In order to have better insight in the quality of input data the estimation of
accuracy of the gravity data and geoid undulations from GPS/levelling data was carried
out using EGM08 geopotential model. It shows a poor quality of GPS/levelling data.
Result of the computation is the gravimetric geoid for the territory of Brunei computed
by collocation method with an accuracy estimated below of ±0.3 m.
