Operation IceBridge File Naming Conventions
This page contains information on the file naming conventions required for Operation IceBridge data files.
- File name must begin with the IceBridge data set shortname (e.g. ILATM1B). The shortname must be all capital letters.
- As a general rule, file names contain fields descriptive of the data file.
- Fields must be separated (delimited) by an underscore.
- A Date field must be included in the file name. Preferred date formats are: YYYYMMDD or YYYYDOY
Additional information should be included in the filename to uniquely identify the file and provide suitable information to data users, including:
- Time of data collection.
- Any additional information that might be needed to uniquely identify the data file. (e.g. sensor type, platform information, etc.).
|File Name Field||Description|

|000047||Time. Format HHMMSS. HH = hours, MM = minutes, SS = seconds. May also include hh = hundredths|
|AAAAA||Place holder for additional relevant information to identify the data file|
