>From: address@hidden >Organization: GMU >Keywords: 200501201830.j0KIUJv2013893 McIDAS AREA GeoTIFF ADDE Hi Ying, >the server is 129.174.124.79 >thank you very much and please let me know what's wrong with my settings I logged on tonight and found the following: 1) the user 'mcadde' was not setup as it should be: - same HOME directory as the user 'mcidas' - not a login account I corrected the definitions for 'mcadde' using 'vipw' as 'root'. 2) the Bourne shell script that installs the ADDE remote server, mcinet2004.sh, was missing from /home/mcidas. I FTPed it from unidata. 3) the remote ADDE server was setup for 'mcadde' as it had been defined before my change to 'mcadde', so it was incorrect. I uninstalled and then reinstalled the remote ADDE server: <as 'root'> cd /home/mcidas sh ./mcinet2004.sh uninstall mcadde sh ./mcinet2004.sh install mcadde 4) there were no DATALOCs defined in the 'ldm' account. After getting the ADDE remote server to work (step 3), the next step is to go through the remote server for access to the RTIMAGES dataset: <as 'ldm'> setenv MCPATH /usr/local/ldm/mcidas/data:/home/mcidas/data:/home/mcidas/help setenv MCTABLE_READ /usr/local/ldm/mcidas/data/MCTABLE.TXT;/home/mcidas/data/ADDESITE.TXT setenv MCTABLE_WRITE /usr/local/ldm/mcidas/data/MCTABLE.TXT cd ~ldm/mcidas/data dataloc.k ADD RTIMAGES unidata.scs.gmu.edu After doing this, 'ldm' can see the RTIMAGES images through the remote ADDE server: dsinfo.k IMAGE RTIMAGES Dataset Names of Type: IMAGE in Group: RTIMAGES Name NumPos Content ------------ ------ -------------------------------------- ANTARCTIC 99999 Antarctic IR Composite EDFLOATER-I 99999 Educational Floater EDFLOATER-II 99999 Educational Floater II GE-39 99999 GOES-East Hemispheric Short IR GE-CO2 99999 GOES-East Hemispheric CO2 GE-IR 99999 GOES-East Hemispheric IR GE-IRTOPO 10 GOES-East IR/TOPO Composite GE-VIS 99999 GOES-East Hemispheric VIS GE-VISTOPO 10 GOES-East VIS/TOPO Composite GE-WV 99999 GOES-East Hemispheric H2O GEW-IR 10 GOES-East/West IR Composite GEW-IRTOPO 10 GOES-East/West IR/TOPO Composite GEW-VIS 10 GOES-East/West VIS Composite GEW-VISTOPO 10 GOES-East/West VIS/TOPO Composite GEW-WV 10 GOES-East/West H2O Composite GW-12 99999 GOES-West Western Long IR GW-39 99999 GOES-West Western Short IR GW-IR 99999 GOES-West Western US IR GW-IRTOPO 10 GOES-West IR/TOPO Composite GW-VIS 99999 GOES-West Western US VIS GW-VISTOPO 10 GOES-West VIS/TOPO Composite GW-WV 99999 GOES-West Western US H2O MDR 99999 Manually Digitized Radar MDRTOPO 10 MDR/TOPO Composite MOLL-IR 99999 Mollweide Composite IR MOLL-IRTOPO 10 Mollweide IR/TOPO Composite MOLL-WV 99999 Mollweide Composite H2O RESFLOATER 99999 Research Floater DSINFO -- done 5) I note that you have a LOT of images in the RTIMAGES dataset: imglist.k RTIMAGES/GE-IR Image file directory listing for:RTIMAGES/GE-IR Pos Satellite/ Date Time Center Band(s) sensor Lat Lon --- ------------- ------------ -------- ---- ---- ------------ 2533 G-12 IMG 16 FEB 05047 00:45:00 0 72 4 imglist.k: done Do you want to be saving this many (2533) images, or have you not setup a mechanism to scour the images? 6) the script that you are running from ~ldm/etc/pqact.conf, ~ldm/mcrun.sh, is setup to write to the GEOTIFF dataset. This dataset needs to be defined in the 'ldm' account. You had previously defined it in the 'mcidas' account where it could be used. The same step was needed in the 'ldm' account: dsserve.k ADD GEOTIFF/GOES GEOT 1 9999 TYPE=IMAGE \"GeoTIFF GOES image I saw that you you had also defined a dataset with group name VISIMAGE in the 'mcidas' account. I did the same in the 'ldm' account: dsserve.k ADD VISIMAGE/GOES12 AREA 1 9999 DIRFILE=/var/data/ldm/gempak/images/sat/GOES-12/4km/VIS/VIS\* \"VIS images in AREA file format 7) I saw that you had a typo in the pqact.conf action to run mcrun.sh: # Convert UNWISC GOES-East VIsible images to GeoTIFF MCIDAS ^pnga2area Q.(UV) (.*) (.*)_IMG (0.65)um (.*) (........) (....) EXEC /usr/local/ldm/mcrun.sh The error was that there was no space between the 'Q.' and the (UV). I added the space. 8) I saw that even though you are requesting all of the UNIWISC (aka MCIDAS) images from atm.geo.nsf.gov, you were only processing the images that get received in the first half of the hour. I changed all ~ldm/etc/pqact.conf entries that specified 'U1' in the pattern to 'U.' After making the changes to ~ldm/etc/pqact.conf in this and the previous step, I verified that I had not made any typos and then sent a HUP signal to pqact: ldmadmin pqactcheck ldmadmin pqactHUP The HUP signal tells pqact to reread its pattern action file, ~ldm/etc/pqact.conf. After making the above changes, I watched while a new GOES-East VIS image was received by the LDM and converted to a GeoTIFF image by the pqact.conf initiated EXEC of 'mcrun.sh'. Now you need to add the appropriate code to ~ldm/mcrun.sh that renames the newly created ~ldm/mcidas/data/GOES0001.tif file to something that you like.
