A Survey on Spherical Spline
نویسنده
چکیده
Spline functions that approximate data given on the sphere are developed in a weighted Sobolev space setting. The exibility of the weights makes possible the choice of the approximating function in a way which emphasizes attributes desirable for the particular application area. Examples show that certain choices of the weight sequences yield known methods. A convergence theorem containing explicit constants yields a usable error bound. Our survey ends with the discussion of spherical splines in geodetically relevant pseudodiierential equations.

A Comparison of Thin Plate and Spherical Splines with Multiple Regression
Thin plate and spherical splines are nonparametric methods suitable for spatial data analysis. Thin plate splines acquire efficient practical and high precision solutions in spatial interpolations. Two components in the model fitting is considered: spatial deviations of data and the model roughness. On the other hand, in parametric regression, the relationship between explanatory and response v...
متن کاملSpherical Spline Solution to a PDE on the Sphere
We use splines on spherical triangulations to approximate the solution of a second order elliptic PDE over the unit sphere. We establish existence and uniqueness of weak solutions in spherical spline spaces and estimate convergence of the spline approximations. We present a computational algorithm and summarize numerical results on convergence rates. §
متن کاملTensor Spherical Harmonics and Tensor Spherical Splines
In this paper, we deal with the problem of spherical interpolation of discretely given data of tensorial type. To this end, spherical tensor elds are investigated and a decomposition formula is described. It is pointed out that the decomposition formula is of importance for the spectral analysis of the gra-vitational tensor in (spaceborne) gradiometry. Tensor spherical harmonics are introduced ...
متن کاملArtifactually high coherences result from using spherical spline computation of scalp current density.
Coherence computed from common reference montages inextricably confounds true coherence with power and phase at the recording and reference electrodes. Direct measurement of coherence requires reference-free EEG data, such as data from EEG scalp current densities (SCDs), which estimate the potential gradient perpendicular to the scalp. Perrin et al. (1989) presented a method for computing SCDs ...
متن کاملLocally Supported Kernels for Spherical Spline Interpolation
By the use of locally supported basis functions for spherical spline interpolation the applicability of this approximation method is spread out since the resulting interpolation matrix is sparse and thus eecient solvers can be used. In this paper we study locally supported kernels in detail. Investigations on the Legendre coeecients allow a characterization of the underlying Hilbert space struc...
