File structure and naming
The old structure is located here.
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 Dirs | 2nd Level Dirs | 3rd Level Dirs | 4th Level Dirs | 5th Level Dirs | 6th Level Dirs | 7th Level Dirs | Example File Formats | Comments | |

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:
