[GRASSLIST:3137] blending seams in patch

[Richard Greenwood]

I have four rasters that I would like to patch. Unfortunately there are
1 or 2 null cells along the common edges, which leave nulls in the
resulting patched map. I would like to simply average "across" the nulls
between adjoining rasters. I tried increasing the region resolution by
8x, but I still have unsightly nulls. Any suggestions?

Thanks,
Rich
