On a similar note, are there any alternatives available to nearest neighbor? For example, kriging? I remember seeing a geostats library in python (hpgl i think), but I found the API rather impractical and difficult to use.

Thanks,

Aman: The basemap interp function is just a convenience function for simple regridding (linear, cubic and nearest neighbor). scipy.interpolate (http://docs.scipy.org/doc/scipy/reference/interpolate.html) provides many more options.

    Juan: On second thought, I'm not sure this is desirable behavior.  I
    would guess that most of the time, if a nearest neighbor is
    masked, the
    user would expect the interpolation routine to return a masked
    value.  I
    would be interested to hear what others think.
