questions about interpolation by NCL

Thanks to Dennis Shea and Lou Wicker.

Indeed, the spectral harmonic method spreads the whole
domain while the bilinear mothed is more local. I've
tried to use linint2_Wrap function to regrid the
topography and its flag(ocean=0,land=1), the results
are relatively rational and acceptable. However, I'm
now puzzled that for what kind of occasions we should
use the f2fsh_Wrap/f2gsh_Wrap and linint2_Wrap, and
which is better of the two kinds of regrid functions?

Thanks.
