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 this wiki page? 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 to the archive location under ~arsf/arsf_data/archived/YYYYMMDD/..<original path from ~arsf/arsf_data/>
   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
   ./archive_helper-justdoit.sh 20080219/2007/flight_data/uk/*
    # note you need to specify dirs at the project level, hence the * above
   

   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
