When using GRIDDATA, you might try setting the SECTORS keyword to a
higher value, like 3 or 4. (You may also need to set EMPTY_SECTORS=0,
I'm not sure of the default.) This should force the procedure to
interpolate only the points that are "well-surrounded" by data, and
hopefully provide a better interpolant. Everything else will be set to
the value of MISSING.

Since I am using GRIDDATA in linear interpolation mode, the SECTORS
options do not apply. However, I am now having luck interpolating
after setting the MISSING keyword.
Thanks,
Matt
