[McIDAS #FBA-307750]: PATH command

Hi Kwan,

Excellent!  I'm glad that PATH is working nicely for you now.

> I am amazed that you modified the program so quickly.

It was a very simple program modification.

> About my last email that you said you'd not seen,

Yes, that was strange.  I know we received the email because
I got an alert that it was received.  It did not, however,
get included with this ticket.

What exactly do you mean by "raw" data.  METEOSAT-8 data
can be written using two different formats that you might
consider to be "raw" since they are not in McIDAS AREA format.
Is this what you mean?

I believe that you can create a McIDAS ADDE dataset using the
"raw" data and read the data that way.  There should be no
need to convert to McIDAS AREA format.  Please review the
DSSERVE command for more information on creating an ADDE dataset
for METEOSAT data.

This should not be needed.  I am sure about this since
EUMETSAT is using McIDAS ADDE to serve realtime METEOSAT-8 data.

Unfortunately no, I don't know of any routines that go from McIDAS AREA
to HRIT.

I assume that you are thinking about taking other imagery and writing it
into HRIT format so that the RDT algorighm will work.  Correct?

Cheers,

Tom
