Geoid Determination by 3D Least-Squares Collocationed by removing the contribution of topographic short wavelength features. It is also described how LSC may be used to determine parameters like a height datum off-set or to detect possible gross errors. Examples using data from New Mexico, USA, illustrates the use of the method.amygdala 发表于 2025-3-29 04:43:12
Geoid Determination by FFT Techniquesnexperienced in spectral methods. Therefore, the Fourier transform and its properties are presented in the appendix following the chapter (Appendix A), and reference is made to the particular formulas and properties employed in geoid determination.AMEND 发表于 2025-3-29 11:11:34

https://doi.org/10.1007/978-3-476-04281-1s. The high-frequency contribution of the topographic and bathymetric effects to gravity-field related quantities (e.g., gravity anomalies, gravity disturbances, geoid undulations, deflections of the vertical, gravity gradients) is primarily due to the strong correlation of the short-wavelength gravity features with topography and bathymetry.生锈 发表于 2025-3-29 18:29:24
