On the placement of latitudes in iso-latitude optimal-dimensionality sampling schemes on the sphere

Khalid, Zubair; Kennedy, Rodney


Optimal-dimensionality sampling schemes for band-limited signals (in spherical harmonic degree) on the sphere have been developed such that the number of samples equals the spectral degrees of freedom. These schemes use iso-latitude rings of samples for the computation of the Spherical Harmonic Transform (SHT) to high accuracy. However, the location of the iso-latitude rings had not been fully optimized to attain the highest possible numerical accuracy of the SHT computation. We study the...[Show more]
