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:

Top level dir	2nd level dir	Example Files with ARSF Format	Comments
admin			Contains the flight logsheet and any miscellaneous information (readme's, copies of trac tickets, etc)
		GB08_02-2009_078a_Delamere.(doc|txt|pdf)	Logsheet
applanix		*.ppc	Raw and processed Applanix navigation (raw files in applanix/raw/DCALM*, final processed data in applanix/*sbet or applanix/Proc/sbet*.out)

	raw	DCALM.???	Raw gps data from plane
atm			Raw ATM data files (az???LLL.JJJ, where ??? = disk id, LLL = 3 digit file number (000 typically contains navigation), JJJ = Julian day of capture), pre-2009 only
calibration			Rypically a symlink to the appropriate calibration directory
casi			Raw CASI data files (ca??LLL.JJJ, where ?? = disk id, LLL = 3 digit file number, JJJ = Julian day of capture), pre-2008 only
delivery			Contains copies of data delivered to end users
	(see below)		Structure described below
dem			Contains azgcorr compatible DEMs
eagle			Raw Eagle data files (.raw = image data, .hdr = ENVI compatible header, .nav = navigation synchronisation data)
	orignal_headers (optional)		If the header files have been altered for any reason, the originals should be in here
grid_logs (deprecated)			Logs from hyperspectral script runs on gridnode (one log per sct run)
hawk			Raw Hawk data files (.raw = image data, .hdr = ENVI compatible header, .nav = navigation synchronisation data)
	original_headers (optional)		If the header files have been altered for any reason, the originals should be in here
leica			Leica LIDAR data
	(see below)		Structure described below
lev1			Processed hyperspectral level 1 data (note this will be the most current, not necessarily what was delivered), see below for filename info
lev3			Processed hyperspectral level 3 data (note this will be the most current, not necessarily what was delivered), see below for filename info
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			ATM processing scripts
runc			CASI processing scripts
rune			Eagle processing scripts
runh			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

Dirs	Files	Comments
	Read_Me.pdf	Instructions for use and description of dataset, plus any problems encountered.
dem		A dem to help the user with processing to lev3. Can be from their lidar data, from SRTM or a combination (not from NEXTMAP data).
doc		azgcorr manual and other documentation
lev1		Processed level 1 data
logsheet		Logsheet as stored in admin/ above
misc		Any additional files needed for level 3 processing (e.g. OS National Grid correction file, geoid-spheroid separation grid file, etc)
screenshots		Images of the level 3 output we managed when testing the data

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
