Arrival of new flight data

This procedure should be followed on receipt of new flight data from ARSF.

If in any doubt about something (e.g. a dataset has two project codes), contact Gary.

Copy the data onto the system

After successfully copying the data onto the system, email arsf-processing to confirm the data transferred ok (but hasn't yet been checked!).

Unpacking projects

It is recommended you create a copy of the data and unpack this, incase anything goes wrong. Once the data has been successfully unpacked and moved to permanent storage the original copy from ops can be removed.

Run -e -p <path_to_project>

This will do three things:

  • Run a series of checks which you should go through and fix if necessary
  • Fix a few things automatically (permissions/common spelling mistakes)
  • Provide a list of commands (if any) that will convert the project from the old style structure to the current standard. These should be checked then pasted into the terminal.

Manual steps

  • Check time stamps of files vs julian day to check we use the correct julian day
  • Prune empty directories (check these aren't stubs for later data first)
  • Rename any remaining spelling mistakes in directories or files. Check hyperspectral raws have VNIR/SWIR/FENIX prefix.
  • Check all data belongs to this flight and move out/delete if belongs to a different flight day.


Manual checks

  • Look at the logsheet and verify that we have copies of all relevant data mentioned there.
    • In some cases, the flight crew may fly two projects back-to-back but enter all the data onto a single logsheet. If so, you may need to split the project directory into two, particularly if there's a large time gap (navigation needs separate processing) or the PIs are different (different delivery addresses/tracking). If you do need to split a project, ensure both copies have copies of common files (logsheets, rinex, etc), but that non-common files are not duplicated (ie. don't include hawk data for part 1 in part 2..). Also note in the ticket what was done for tracking purposes.
  • Check the filesizes of all data files (Eagle, Hawk, ATM, CASI) to make sure none are zero bytes (or obviously broken in some way).
  • Verify the details on the logsheet (esp. PI) by calling/emailing ARSF-Ops (probably Gary) - the application form and logsheet are not reliable enough, nor do they track any changes in PI over the lifetime of the application. Get the alpha grading as well.

Move to permanent PML data storage

Move to appropriate location in the repository (~arsf/arsf_data/2011/flight_data/...)

  • ensure the project directory names conform to the standard - PROJECTCODE-YYYY_JJJxx_SITENAME, e.g. GB07_07-2007_102a_Inverclyde, boresight-2007_198, etc

Generate Logsheet

Make a logsheet that is suitable for delivery to end users. Use the script and follow instructions from:

  • Run from top level - writes into 'admin' dir. You may wish to rename this dir before running to prevent any accidental overwriting.
  • Fill in the yellow boxes with information from supplied logsheet.
  • Blue boxes should be automatically filled in when you start the program but check the values are correct (or at least that they appear so).
  • Click 'fill post manual'. This will calculate the values for the green fields based on the values you have entered into the yellow fields. You should also check that these fields look correct. If the flight was flown over midnight, you may need to correct them.

Tickets and tracking

Status Page

Add details to the processing status page. Under 'Data location' use the full path to the project and do NOT include server name (e.g use /users/rsg/arsf/... and not /data/vishyuan/...).


Raise a new trac ticket (type 'flight processing') for the new data.

  • Ticket summary should be of the form EU10/03, flight day 172/2011, Dennys Wood
  • Add short version of scientific purpose to guide processing (check ARSF application in ~arsf/arsf_data/2009/ARSF_Applications)
  • Note arrival time of data
  • Set priority of ticket from project grading (try the grades subpages on Projects or hassle ARSF-Ops)
  • Note any specific comments that might help with processing
  • Owner should be blank
  • Verify the sensors that were requested in the application (primary) and those that weren't (secondary). Note in the ticket which these were.
  • Ticket body should contain:
    Data location: ~arsf/arsf_data/2011/flight_data/..... FILL IN
    Data arrived from ARSF via SATA disk LETTER OR network transfer on DATE.
    Scientific objective: FILL IN FROM APPLICATION (just enough to guide processing choices)
    Priority: FILL IN FROM APPLICATION/WIKI PAGE (e.g. alpha-5 low), set ticket priority appropriately
    PI: A. N. Other
    EUFAR Project ID:
    CAFAM code: 
    Any other notes..
    = Sensors: =
     * Eagle (requested)
     * Hawk  (requested)
     * Leica LIDAR (not requested but flown anyway)
     * RCD (requested)

Create KML overview

When happy the directory is unpacked correctly run This will generate the web page and quicklooks of the data that are made available to the user. It will also generate a password which should be included in the email below. Check the username and password works by commenting out the following line:

Allow from env=internal_proxy

from processing/kml_overview/.htaccess as this means a password isn't required for internal access. Remember to uncomment once you have finished.


If the site is in the UK, check the vector page to see if we have vectors for the site in question. If not then email ARSF-Ops (Gary) and ask for them, specifying the corner points of the area covered, in OS BNG grid coordinates. Use (needs to be ran in the project directory) or use the generated nextmap DEM (below) to get the range of tiles, then do the conversion. It can take a couple of weeks before we get the vectors.

E-mail PI

Email the PI to inform them that their data has arrived for processing. Sample text:

    • the date of arrival should be when the disks arrived or when the download begun
    • the username and password are available in the .htaccess file in processing/kml_overview or ~arsf/usr/share/kmlpasswords.csv. Note that will need to have been run to create a password first unless the project code already exists for previous data.
  • cc to arsf-processing
  • also cc to
  • set reply-to to arsf-processing
  • subject: ARSF data arrival notification (<PROJECT> [<EUFAR ID>])
    Dear <PI_NAME>,
    This is a notification that your ARSF data for <PROJECT> [<EUFAR ID>], flown on
    <CALENDAR_DAY(S)>, are at the ARSF Data Analysis Node for processing (data
    received from ARSF Operations on <DATE_OF_ARRIVAL>).
    We aim to deliver as quickly as possible - our current processing 
    priority order can be found at 
    though please note that this queue is subject to change.
    You can follow progress at the following webpages:

      - general status page
      - our notes during processing (may be technical)
    Also available are KML (Google Earth) files that will allow you to view flight data 
    coverage. These files are updated as the data are processed and more information 
    becomes available. Click the following link and enter username and password details as 
    username: <USERNAME>
    password: <PASSWORD>
    Further information on KML previews:

    If there are any specific processing requirements, or if you have additional data that may help with the processing (e.g. GPS basestation data, ground or atmospheric measurements), please contact us directly so we can take account of this before beginning processing.
    If you would like any more information, please feel free to contact us at


Check there is basestation data for the flight. If not, ask ops if they have some or if we need to download it.
