Terrestrial, Atmospheric and Oceanic SciencesThis study aims to introduce the geoid modeling process in Sulawesi and demonstrate the practical issues faced. There are limitations of terrestrial gravity surveys in Sulawesi due to its complex geography, so airborne gravity surveys were conducted from

GEOID '88: A gravimetric geoid for Canada [PDF]
Using Stokes' formula, a gravimetric geoid was calculated for Canada. The input data are as follows: 15 x 15' block averages were used for Canada and the USA and 1 x 1 deg block averages and satellite model (GEM-T1) provided values for the remaining part

On the topographic effects by Stokes’ formula
Journal of Geodetic Science, 2014 Traditional gravimetric geoid determination relieson Stokes’ formula with removal and restoration of thetopographic effects. It is shown that this solution is in errorof the order of the quasigeoid-to-geoid difference, which ismainly due to incomplete ...

Evropski in globalni model geoida na območju Slovenije [PDF]
Geodetski Vestnik, 2000 Article deals with geoid models EGM96 and EGG97. Model geoidundulations are verified by means of given geoid undulations that werecomputed from measured orthometric and elipsoidal heights.

Assessment of marine geoid models by ship-borne GNSS profiles
Geodesy and Cartography, 2017 Even though the entire Baltic Sea is included in previous geoid modelling projects such as the NKG2015 and EGG07, the accuracy of contemporary geoid models over marine areas remains unknown, presumably being offshore around 15–20 cm. An important part of

Mantle plumes on Venus revisited [PDF]
The Equatorial Highlands of Venus consist of a series of quasicircular regions of high topography, rising up to about 5 km above the mean planetary radius.

GRAVSAT error analysis by means of global spectral analyses of the marine geoid from SEASAT altimeter data [PDF]
The geographical variability of short wavelength geoid power spectra (geoid roughness), was mapped for the world's oceans between latitudes 72 deg N and 72 deg S. A spectral analysis of SEASAT altimeter data, reduced to sea surface heights, was performed

Gravity and geoid anomalies of the Philippine Sea: Evidence on the depth of compensation for the negative residual water depth anomaly [PDF]
A negative free-air gravity anomaly which occurs in the central part of the Philippine Sea was examined to determine the distribution and nature of possible regional mass excesses or deficiencies. Geoid anomalies from GEOS-3 observation were positive.
