Does your spatial database have points surrounding the location 
associated with the error. Nearest interpolation allows extrapolation 
but linear interpolation does not.

If your points have a very irregular distribution in space, then try 
adding/removing points so that the spatial distribution is more uniform 
or has more gradual transition from coarse to fine spacing.
