[LDM #NSP-325161]: how to retrieve the VOS (volunteer observing ship) data via LDM.

Yes, I saw Gilbert's response to your post on address@hidden

"FM 13âXI Ext. SHIP" is a reference to a WMO document in which the structure
of the WMO id is described.  What you need is what the WMO IDs look like.

From his response to Gilbert's information, it looks like Gerry Creager
(formerly employed at TAMU and is still associated with TAMU) knows how
to use the information in the WMO document to come up with the needed
extended regular expression to use in an LDM pattern-action file action
to process SHIP reports which should include VOS reports.

TAMU has historically been an avid use of GEMPAK, and GEMPAK has
LDM/IDD pattern-action file actions that are labeled as being used
for SHIP, CMAN and BUOY data.  Here are the two actions that I see
provided with GEMPAK for those observations:

# ship, buoy and CMAN
        PIPE    dcmsfc -b 9 -a 10000
        -d data/gempak/logs/dcmsfc.log
        -e GEMTBL=/home/gempak/NAWIPS/gempak/tables
# 6 Hour Ship Observations
WMO     (^S[IMN]V[^GINS])|(^S[IMN]W[^KZ])
        PIPE    dcmsfc -d data/gempak/logs/dcmsfc_6hr.log -a 6
        -e GEMTBL=/home/gempak/NAWIPS/gempak/tables

These actions PIPE the reports to a GEMPAK decoder, so they are probably not
quite what you want.  The extended regular expressions, however, should be





- are you working with Gerry, Donna Cote, Neil Smith or someone else at TAMU?

  If yes, they should be able to help you craft the pattern-action file
  action(s) you need.
