File structure and naming

A single site/logical group of flight lines/sortie should be contained in a single directory. If there are multiple sites from different projects, significantly different times of overflight or large time gaps, each should have its own directory.

The directory name should look like: PROJECTCODE-YYYY_JJJxx_SITENAME, e.g. GB07_07-2007_102a_Inverclyde, boresight-2007_198, etc.

There should be:

  • no spaces, brackets or other Unix-upsetting characters in filenames
  • execute permission removed from anything non-executable
  • no empty directories? (need to think about this, maybe only do after checking it's not a stub for later data)

The structure under the project directory should look like:

raw DCALM.001 Raw gps data from plane

(see below) Structure described below
lev1 Processed hyperspectral level 1 data (should be empty if data has been moved into delivery)
lev3 Processed hyperspectral level 3 data
e078a013b_n_sct-0.03_p_gpt0.0.tif
lidar (deprecated) Raw and processed ULM LIDAR (raw LIDAR looks like "surveyXXX.range", processed is typically in a strips/ directory)
logs *.logs Logs from hyperspectral script runs on gridnode (one log per flightline)
photos (deprecated) RC10 scanned aerial photographs
rinex GPS basestation data appropriate to the site
runa (deprecated) ATM processing scripts
runc (deprecated) CASI processing scripts
rune (deprecated) Eagle processing scripts
runh (deprecated) Hawk processing scripts
tabi Raw TABI data
vectors (2007/8 only) - symlink to appropriate vectors

The lev1 and lev3 data filenames are structured as "sdddfnn1b.{hdf|tif}", where:

  • s is the sensor id (a=ATM, c=CASI, e=Eagle, h=Hawk)
  • ddd is the Julian day of the data acquisition
  • f distinguishes between multiple flights on the same day (“a” being the first flight)
  • nn is the flight line number (note this is not necessarily the same as the flight line identifier as specified by the PI - these numbers are the number of the flight in order of when it was taken, as on the logsheet)

Delivered data

As data may be delivered multiple times (in the event of a problem requiring reprocessing) or in stages (if particular sensors are completed first and others look like they'll be delayed), we take copies of any data sent to the end user for future reference (e.g. in support). The lev1/ and lev3/ directories will typically contain the latest processed version.

Delivered data is stored delivery/YYYYMMDD/PROJECTCODE/, where YYYYMMDD is the date the delivery was created. The directory structure of a delivery looks like:

Hyperspectral data

(eagle|hawk)_mosaic.jpg Screenshot of all level 3 data
(eagle|hawk_mosaic_with_vectors.jpg Screenshot of all level 3 data with overlaid vectors

The image filenames in the lev1 directory are structured as sdddfnnLL.hdf, where:

  • s is the sensor id (a=ATM, c=CASI, e=Eagle, h=Hawk)
  • ddd is the Julian day of the data acquisition
  • f distinguishes between multiple flights on the same day ("a" being the first flight)
  • nn is the flight line number
  • LL is the processing level
    • 1b = ungeocorrected data
    • 3a = geocorrected without a DEM
    • 3b = geocorrected with a DEM
