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'.
All sensors need to be delivered and r-synced. Run rsync with a --dry-run to check it is all up to date. Check with whoever processed each sensor if need be.

1. Move workspace project into workspace/being_archived
2. Prepare the repository version for archiving:
   1. Make sure everything is present and where it should be! (see Processing/FilenameConventions for the required layout and name formats)
      Things to look out for: Delivery folders, applanix/rinex data, las files, DEMs.
      Use proj_tidy.sh to highlight any problems:

      proj_tidy.sh -p <project directory> [-ed]
      
      Options:
      -e Extended check (may be verbosey) 
      -d Delivery mode (Checks deliveries only)
      

   2. 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
      

   3. Delete the contents of the lev1/ subdirectory, where these are duplicates of the delivery directory.
   4. 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), hidden files etc
      2. Find all files/dirs with unusual characters (space, brackets, etc):

         find -regex '.*[^-0-9a-zA-Z/._].*' | ~arsf/usr/bin/fix_naughty_chars.py
         

         This will give suggested commands, but check first.
   5. Set permissions:
      1. Remove executable bit on all files (except the point cloud filter and the run[aceh] scripts):

         find -type f -not -wholename '*pt_cloud_filter*' -and -not -regex '.*/run[aceh]/.*sh' -and -perm /a=x -exec chmod a-x {} \;
         

      2. Give everyone read permissions (and execute if it has user execute) for the current directory and below:

         chmod -R a+rX .
         

3. Create an archive tarball for NEODC to download:

   su - arsf
   cd ~/arsf_data/archived/
   ./qsub_archiver.sh <path to project in repository>
   (e.g. ~arsf/arsf_data/2008/flight_data/uk/CEH08_01)
    # Note you need to specify dirs at the project level
    # To run the archiving locally rather than via the grid engine, use:
   ./archive_helper-justdoit.sh ~arsf/arsf_data/2008/flight_data/uk/CEH08_01
   

   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.
   
   
4. Notify NEODC they can download the data.
5. When NEODC have the data:
   1. Remove it from the transfer area
   2. Note on ticket that it's been sent to neodc (with date.)
6. When NEODC confirm they have backed up the data:
   1. Move the repository project to non-backed-up space at: ~arsf/arsf_data/archived/<original path from ~arsf/arsf_data/>
      e.g. mv ~arsf/arsf_data/2008/flight_data/uk/CEH08_01/ ~arsf/arsf_data/archived/2008/flight_data/uk/CEH08_01
      You may need to create parent directories if they don't yet exist.
   2. Create a symlink to the project in it's original location. Point the symlink through ~arsf/arsf_data/archived rather than directly to larsen.
      e.g. ln -s ~arsf/arsf_data/archived/2008/flight_data/uk/CEH08_01 ~arsf/arsf_data/2008/flight_data/uk/CEH08_01
   3. Note in ticket that it has been backed up NEODC and give new data location.
7. When NEODC confirm that everything appears to be in order (maybe wait a week):
   • Close the ticket
   • Delete the workspace copy in being_archived
