Re: IDV and netCDF FillValue

Hi Brian-

Sorry for the delay in responding.  I was on vacation and your
message got lost in my mailbox.

Hi.  I'm new IDV user.

Welcome.

I'm using IDV for visualization of ocean
model output that has been mapped to a
regular grid.  The points over land are set
to _FillValue=nf90_fill_value, but contours get
drawn with a max value on the range of
nf90_fill_value.

What does the attribute look like in ncdump?  Is it
    var:__FillValue = "nf90_fill_value" ;

or has the macro been expanded (as it should be).
It will only work if the value is numeric.

Does IDV recognize netCDF FillValues?

It should.  Can you provide me with a sample file?
