If not, the answer to your query is that the compositing of imagery is a process that is done locally on your machine. In order for this to work, the copy of ROUTE.SYS that you put in the directory into which you are decoding imagery must have the compositing actions activated. This is done through a McIDAS-X session by: o start a McIDAS-X session as the user 'mcidas' <login as 'mcidas'> mcidas o definining a REDIRECTion to the copy of ROUTE.SYS in the output data directory: REDRIECT ADD ROUTE.SYS "/mcidasdata/mcidas o verify that the REDIRECT command worked: DMAP ROUTE.SYS o add a REDIRECTion for SYSKEY.TAB which should also be in the output data directory REIDRECT ADD ROUTE.SYS "/mcidasdata/mcidas o verify that REDIRECTion DMAP SYSKEY.TAB o see if compositing entries are in the copy of ROUTE.SYS that you can now access: ROUTE LIST The compositing entries have product codes of CI, CV, and CW. The listing should look like: CI GOES-E/W IR Composite 80-89 AREA0086 00293 1936 none 3 CV GOES-E/W VIS Composite 90-99 AREA0097 00293 1937 none 3 CW GOES-E/W H2O Composite 70-79 AREA0074 00293 1936 none 3 If the first column of the listing starts with an 's', then the entry is SUSpended, and you need to RELease (unSUSpend) it: ROUTE REL CI CV CW While you are at it, you should also make sure that your routing table has entries for the CIMSS products that were added to the Unidata-Wisconsin datastream back in June. Those entries will look like: CA Cloud Top Pressure 1100-1109 AREA1104 00293 1915 CTP.BAT 3 CB Precipitable Water 1110-1119 AREA1110 00293 1946 PW.BAT 3 CC Sea Sfc. Temperature 1120-1129 AREA1122 00293 1835 SST.BAT 3 CD Lifted Index 1130-1139 AREA1134 00293 1948 LI.BAT 3 CE CAPE 1140-1149 AREA1143 00293 2004 CAPE.BAT 3 CF Ozone 1150-1159 AREA1158 00293 2005 OZONE.BAT 3 If you do not have entries htat look like these (never mind the AREA file numbers and dates/times), then you need to do the following: cd ~mcidas/workdata ftp ftp.unidata.ucar.edu anonymous your_email_address cd pub/mcidas get CIMSS.BAT quit <start a McIDAS-X session as 'mcidas' again> BATCH CIMSS.BAT After doing this, your routing table should look similar to the listing above. The second part of getting the compositing working on your machine is to make sure that you have configured the 'batch.k' shell script sent out with ldm-mcidas to match your McIDAS-X installation. This is done most easily by: o creating a ~ldm/decoders directory as the user 'ldm' (assuming that 'ldm' is the user acccount in which you installed the LDM) o make a decoders directory: cd ~ldm mkdir decoders o add ~ldm/decoders to the PATH of user 'ldm'. Do this in 'ldm's shell environment definition file, .cshrc (for C shell) and make the new PATH active: source .cshrc o copy the version of 'batch.k' from the ldm-mcidas bin directory (binary distribution; it is in the src/decode directory in the source distribution) to ~ldm/decoders. Also copy all of the other ldm-mcidas decoder binaries to this same directory o edit ~ldm/decoders/batch.k and set MCHOME, MCDATA, MCGUI, MCLOG, PATH, and potentially LD_LIBRARY_PATH to match your McIDAS-X and system setup o make sure that ~ldm/decoders/batch.k is set to be executable chmod +x batch.k After doing the above, compositing of the GOES-East and GOES-West images should proceed. I am sorry that I did not have the opportunity to respond, but I have been on travel. >M.
