Unidata-Wisconsin and FNEXRAD Imagery Users:

ldm-mcidas Version 2002b is now available for download.

What is ldm-mcidas:

    ldm-mcidas is a package of LDM compatible decoders for imagery
    products from the IDD MCIDAS/UNIWISC (Unidata-Wisconsin
    datastream), FNEXRAD (composite NEXRAD Level III products created
    by the UPC), and NIMAGE (NOAAPORT GOES-East/West imagery in GINI
    format) datastreams.  It also contains McIDAS-specific LDM decoders
    for NLDN lightning and FSL wind profiler data.

Who uses ldm-mcidas:

    If you ingest Unidata-Wisconsin, FNEXRAD, or NIMAGE imagery through
    the IDD for use in any UPC-supported application (e.g., GEMPAK, IDV,
    or McIDAS), you most likely use ldm-mcidas decoders.

The last ldm-mcidas version I was aware of was 7.8.0.  Did I miss an upgrade:

    The previous release of ldm-mcidas was numbered 7.8.0.  The version
    numbering of the ldm-mcidas packages matches the Unidata McIDAS-X
    release against which it gets linked.  Unidata McIDAS-X Version
    2002b will be available in mid-January.

When should I upgrade to ldm-mcidas v2002b:

    You need to perform the upgrade to v2002b before mid-January when
    we will be adding two new CIMSS Wildfire ABBA products to the
    Unidata-Wisconsin datasream.  For more information on the products
    that will be added, please refer to:

    http://cimss.ssec.wisc.edu/goes/burn/wfabba.html

What problems were fixed in ldm-mcidas v2002b:

    1) the decoder for PNG compressed images in AREA file format would
       corrupt the McIDAS routing table, ROUTE.SYS, upon receipt of
       images whose product codes were not contained in the routing table.

    2) the FSL wind profiler decoder, proftomd, was creating numerous,
       hidden, zero-length files in the directory from which the LDM was
       run.  Also, this decoder would go into an infinite loop and use all
       of a system's available CPU under RedHat 8.0.

    3) the example LDM pqact.conf file, ldm-mcidas-pqact.conf, contained
       in the release has been updated with typo corrections.  The
       McIDAS routing table, ROUTE.SYS, contained in the distribution
       has been updated to include entries for new CIMSS products that
       will be added to the Unidata-Wisconsin datastream.

What operating systems is ldm-mcidas v2002b available for:

    Source distribution:
    --------------------

    A source distribution of v2002b is available in the pub/ldm-mcidas
    directory of anonymous FTP on ftp.unidata.ucar.edu in the file
    ldm-mcidas-2002b.tar.Z.  Virtually all sites should, however, be
    able to use one of the binary distributions we make available.  If
    for some reason you can not use a binary release, we are available
    to help you build the decoders from source.  Be aware that you must
    be licensed for and have installed Unidata McIDAS in order to build
    ldm-mcidas from source.

    Binary distributions:
    ---------------------

    Binary distributions are available from operating system-specific
    directories of anonymous FTP on ftp.unidata.ucar.edu:

    Directory                     Operating system
    -----------------------------+----------------------------
    pub/binary/osf1_5.1-alpha     Compaq OSF/1 5.1
    pub/binary/hpux_11.00-hp9000  HP HP-UX 11.0
    pub/binary/freebsd_4.5-i386   FreeBSD 4.5
    pub/binary/freebsd_4.7-i386   FreeBSD 4.7
    pub/binary/aix_4.3-rs6000     IBM AIX 4.3
    pub/binary/irix_6.5-mips      SGI Irix 6.5
    pub/binary/irix64_6.5-mips    SGI Irix64 6.5
    pub/binary/sunos_5.7-i86pc    Sun Solaris i86pc Version 2.7
    pub/binary/sunos_5.8-i86pc    Sun Solaris i86pc Version 2.8
    pub/binary/sunos_5.6-sparc    Sun Solaris SPARC Version 2.6
    pub/binary/sunos_5.8-sparc    Sun Solaris SPARC Version 2.8
    pub/binary/sunos_5.9-sparc    Sun Solaris SPARC Version 2.9
    pub/binary/linux_2.2-i686     RedHat 6.[12] Linux
    pub/binary/linux_2.4-i686     RedHat 7.x Linux
    pub/binary/linux8_2.4-i686    RedHat 8.0 Linux

    If your operating system is not included in the above list, you
    should still be able to use a binary built for a previous release
    of the OS you are using.

    NOTE: In all cases (source and binary), the distribution compressed
    tar file should be FTPed in binary mode!

How do I upgrade the ldm-mcidas decoders I am currently using:

    The web pages for the ldm-mcidas package available from:

    http://my.unidata.ucar.edu/content/software/mcidas/mcidd/index.html
    
    contain instructions for obtaining, building (if necessary), installing,
    and using the ldm-mcidas decoders with the Unidata LDM.

    Sites currently using ldm-mcidas should be able to upgrade with a
    minimum of effort:

    1) FTP the new ldm-mcidas release to the HOME directory of the 'ldm'
       account (~ldm) in binary mode and unpack the new distribution.

    2) CD to the ~ldm/ldm-mcidas-2002b/bin directory and copy the decoders
       you will be using to the directory you will run them from.  This
       is typically the ~ldm/decoders or ~ldm/util directory.

    3) cd to the ~ldm/ldm-mcidas-2002b/etc directory and copy the files
       SATANNOT and SATBAND to the ~ldm/etc directory.

    4) The next step depends on how you currently have ldm-mcidas decoders
       configured on your system:

       McIDAS users, or users that have pqact.conf entries that specify
       use of the McIDAS routing table (as indicated by the '-r \1,\2'
       flag specifed in a pnga2area action):

           If you have McIDAS installed:
           -----------------------------

             o FTP the upgrade BATCH file WF_RTE.BAT from the
               pub/mcidas/data directory of anonymous FTP on our
               FTP server, ftp.unidata.ucar.edu, to the ~mcidas/workdata
               directory.  

             o verify that your McIDAS installation is setup to point
               at the copy of ROUTE.SYS that is being updated by your
               ldm-mcidas decoders:

               dmap.k ROUTE.SYS

               If you are not pointing at the copy of ROUTE.SYS that is
               being updated by your ldm-mcidas decoders, setup a file
               REDIRECTion to point at it:

               redirect.k ADD ROUTE.SYS \"directory_being_updated_by_ldm-mcidas

             o update the copy of ROUTE.SYS that is being updated by your
               ldm-mcidas decoders:

               batch.k WF_RTE.BAT

           If you do NOT have McIDAS installed:
           ------------------------------------

             o update the copy of ROUTE.SYS that is being updated by your
               ldm-mcidas decoders by copying
               ~ldm/ldm-mcidas-2002b/etc/ROUTE.SYS to the directory in
               which you are decoding the Unidata-Wisconsin imagery
               (the '-d' flag specified in your pqact.conf pnga2area
               action specifies the location of this directory).

        GEMPAK users and users that are not using the McIDAS routing table:

           o extract the actions from the example pqact.conf file,
             ~ldm/ldm-mcidas-2002b/etc/ldm-mcidas-pqact.conf, for
             the Northern and Southern Hemisphere Wildfire ABBA products;
             modify them as needed; and add them to your
             ~ldm/etc/pqact.conf file.

    5) after making any change to the LDM pqact.conf file (~ldm/etc/pqact.conf)
       verify that there are no typos using 'ldmadmin pqactcheck'.
       After correcting any typos, send a HUP signal to pqact telling
       it to reread the pqact.conf file: 'ldmadmin pqactHUP'.

How do get help upgrading to ldm-mcidas v2002b:
