What is the .VICAR File Extension?

.VICAR File Extension Description:

The file extension VICAR is used as a graphics file by the application named VICAR. The VICAR file extension is related to the VIC and IMG file extensions.

VICAR is an acronym for Video Image Communications and Retrieval. This is a compilation of applications that processes images that is supported by MIPL or Multimission Image Processing Laboratory, located at the JPL or Jet Propulsion Laboratory. VICAR is primarily used for analyzing and working with spacecraft images. The image formats used by VICAR applications would have the VICAR file extension as well, as most of the data from missions that are managed by JPL would use the VICAR file extension. These imaging data comes from outer planets missions including Voyager missions, Lander missions to Mars, and Mariner missions to different planets.

The VICAR format was originally created for use with the IBM 360/44 programming system. Later on it was transported for to with IBM OS/360, VAX-VMS and Alpha-VMS. Today, files with the VICAR file extension runs with software having the Sun-Solaris and x86-Linux platform.

Files with the VICAR file extension would have a file header that is usually encoded in the ASCII text format. These files would also have a metadata and image data that are all stored line after line of its individual records, and are stored in a binary format. Basically, these files would have three main components, the labels part, the image part, and the EOL labels part. On the image part, it is further subdivided into three components, the binary header, the binary prefix, and finally the image pixels.

VICAR file extensions were first stored in magnetic tapes, but because of the physical deterioration of these mediums, these storage devices became very inefficient. Later on, these VICAR file extensions were stored in CDs, and the public domain software, when used by succeeding missions accesses these CD based data. In the conversion from magnetic tapes to CD, the VICAR file extension was retained, and still used up to the present.
