Fitting Smooth Paths to Spherical Data

Abstract: Given a set of data points on the sphere at known times, one often wishes to fit a smooth path to the data. In this paper we propose a unified approach to deal with such problems. Our method can be described as “unwrapping” the data onto the plane, where standard curve fitting techniques can then be applied. As an important example of our approach, we define and fit “spherical spline functions”.
