[gradsusr] Find nearest valid data

[Sam Wilson]

Hi,

I came across the following issue and am having the same problem but never saw a response:

<http://gradsusr.org/pipermail/gradsusr/2010-July/028033.html><http://gradsusr.org/pipermail/gradsusr/2010-July/028033.html>
http://gradsusr.org/pipermail/gradsusr/2010-July/028033.html

I know by default GrADS will return data from the nearest grid point to the lat/lon specified.  Is there any sort of function that will return the nearest non-undefined data?

Thanks,
Sam
