missing data - interpolation

Hi All,

I am working with ocean data, and when I use the cnFillMode=AreaFill for my
contour maps, I get a jagged boxed coastline around the coastlines, due to
the missing data.
When, I use cnFillMode=RasterFill, then the grids match up to the coastline
pretty well, but I would much rather have smooth contour lines with the
AreaFill.

The AreaFill jagged looking data around the coastline is not too
aesthetically pleasing, so I was wondering if you have thoughts about
working around this.

In the past I created my own interpolation function, but this required me to
manually hand pick out the missing data grids I wanted to interpolate so
that the contours would go all the way past the coastline. This is very time
consuming! The map draw is PostFill so it will cover up any data underneath
the land.

Is it possible to just be able to interpolate all the missing data?

Or, what if we could use AreaFill, but then RasterFill for areas that are
surrounded by missing dat?

Please let me know if you have any ideas.

Thanks!

Micah
