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
  • Version identification
  • Any additional information that might be needed to uniquely identify the data file. (e.g. sensor type, platform information, etc.)

Filename example:

ILATM1B_V01_20100421_09452366_A.dat

Where:

Table 1. File Name Fields and Descriptions
