Does anyone have information on approximation or interpolation
routines in spherical coordinates?  I am interpolating air
temperature data on the surface of the earth and would like
to compare methods.  Currently, I only have simple inverse-
distance routines (Willmott et al, 1985, Am. Cart.) and a
polyhedron-based method (Renka, 1984, ACM Trans. Math. Soft.).
Specifically, it would be nice to have spherical B-spline
routines or a spherical version of Akima's bivariate interpolant.
I will summarize on the net if there is sufficient interest.
