NEODC Data Delivery

This page documents the procedure to follow when delivering data to NEODC.

First, we need to have some data to send - these should be datasets that are 'completed'.

Work in progress'''

  1. Prepare the relevant datasets:
    1. Make sure everything is where it should be! (see Processing/FilenameConventions for the layout)
    2. Check everything is there (PDF logsheet, delivery directories, scripts, applanix/rinex data)
    3. Add a copy of the relevant trac ticket(s) ; run:
      mkdir -p admin/trac_ticket
      pushd admin/trac_ticket
      wget --recursive --level 1 --convert-links --html-extension http://arsf-dan.nerc.ac.uk/trac/ticket/TICKETNUMBER
      popd
      
    4. Delete the contents of the lev1/ subdirectory, where these are duplicates of the delivery directory.
  2. Scan the filesystem for any 'bad' things and fix them:
    1. delete any unnecessary files - backups of DEMs that weren't used, temp files created by gedit (~ at end of filename), etc
    2. Remove executable bit on all files (except bin/az* and the run[aceh] scripts) -> find -type f -not -wholename '*bin/az*' -and -not -regex '.*/run[aceh]/.*sh' -and -perm /a=x -exec chmod a-x {} \;
    3. Find all files/dirs with unusual characters (space, brackets, etc) - use find -regex '.*[^-0-9a-zA-Z/._].*' | ~arsf/usr/bin/fix_naughty_chars.py to give suggested commands, but check first
    4. Give everyone read permissions (and execute if it has user execute) for the current directory and below - chmod -R a+rX .
  3. Request DTG archives the data
    1. note request on ticket
    2. switch ticket component to "archiving" for ease of tracking.
  4. When DTG completes the archiving (on date YYYYMMDD):
    1. Create a directory as /data/larsenb1/archived/arsf/YYYYMMDD/..<original path from ~arsf/arsf_data/> and move the data to it
      1. e.g. ~arsf/2008/flight_data/uk/CEH08_01... backed up on 1st Feb 2009 would be /data/larsenb1/archived/arsf/20090201/2008/flight_data/uk/CEH08_01...
    2. Create a symlink in ~arsf/arsf_data/archived to the archived data at /data/larsenb1/archived/arsf/YYYYMMDD/
    3. copy and delete the DTG metadata from ~utils/logs/archiving_scratch/arsf... to ~arsf/dtg_archive_metadata/YYYYMMDD/....
  5. Create an archive tarball for NEODC to download:
    su - arsf
    cd ~/arsf_data/archived/
     # figure out what you want to archive, e.g. all in 20080219 archive dir, then
    qsub_archiver.sh 20080219/2007/flight_data/uk/*
     # note you need to specify dirs at the project level, hence the * above
    
     # To run the archiving locally rather than via the grid engine, use:
    ./archive_helper-justdoit.sh 20080219/2007/flight_data/uk/*
    
    1. When complete, this will have dumped the data into ~arsf/arsf_data/archived/neodc_transfer_area/staging/. Check it looks ok then move it up one level so NEODC can rsync it.
  6. Notify NEODC they can download the data.
  7. When NEODC have the data:
    • remove it from the transfer area
    • note on ticket that it's been archived/sent to neodc
    • close the ticket
