[McIDAS #AKF-916378]: Open Archive & GEOARC for FY2G Imagery

Did you go through the MCFETCH tutorial?

You say that you downloaded "AREA files from their server".  Did you
actually download imagery in AREA file format?  If yes, then you will
need to setup a local ADDE dataset to access the imagery in those
files.  You've done this before...

The files you attached are all ASCII text and they all tell of
errors.

re:
> 1. Can you please guide me how to use it?

If you downloaded imagery in AREA file format, the following applies:

- where did you put the AREA files that you downloaded?

- let's assume that you downloaded several AREA files and put them
  in your /home/mcidas/workdata/FY2G directory

  You would then create an ADDE dataset for these images.  The first
  question is how these files are named?  If they have the long standing
  AREAnnn naming convention (e.g., AREA0001 ... AREA9999), then you
  could create a local dataset to access the images as follows:

  DSSERVE ADD FY2G/BAND01 AREA DIRFILE=/home/mcidas/workdata/FY2G/AREA* "FY2G 
band 1 imagery from the SSEC Data Center

- assuming the last step, you would then access the imagery using standard
  McIDAS IMG* commands.  For example:

  IMGLIST FY2G/BAND01

  IMGLIST FY2G/BAND01.ALL

  IMGLIST FY2G/BAND01 FORM=ALL

  etc.

re:

The files you attached are definitely not imagery, and they are definitely
not in AREA file format.

re:
> 3. i used the DATALOC ADD A ARCSERV2.SSEC.WISC.EDU command to access the
> FY2G data, but no data available.

Remember that when you download imagery to your own system, you need
to setup your own ADDE dataset to access the imagery.  You have done
this before...

re:

The MCFETCH tutorial is the place to look for information on how to
download imagery in AREA format.  Since I did not develop MCFETCH,
I am not the best one to answer this question.

re:
> I have an API key, if you can test it and check the process.

Is this what you did?  If yes, what were the results?

Cheers,

Tom
