SIR to IFF Conversion: FAQ

What are SIR files?

SIR is also known as a BYU-MERS format and is associated with images used by organizations such as NASA to store space captions of planet earth and data related to them. The format was developed by a group of researchers on Microwave Earth Remote Sensing (MERS), at the Brigham Young University (BYU) and is considered rare.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer.
