The aim of this site is to document the CIS/COD raster image file format that was developed in the 1990s. An upcoming series of posts will illuminate various aspects of the format, for example, its history, technology, and use.

Archived CIS/COD Images
The Internet Archive is a crucial tool for my research. Without it, understanding the companies, locations, dates, and people related to the CIS/COD image format would have been close to impossible. It also archived much of the software to handle the images that was available online in the 1990s.

Companies, Locations, Dates, and People
Our first post explains that “cod” very likely stands for “coded” (image) but does not explain what “cis” means. TL;DR: It’s the acronym for Computer and Information Sciences, Inc., a company that was involved in the implementation of the Lightning Strike image codec.

Understanding the CIS/COD image file format
In an attempt to reverse-engineer the file format of D-Sat 1 I discovered that the satellite images are stored using the Lightning Strike image format. There exists little information about that format and no current software to open and view the files. The goal of this web site is to collect as much information as possible about the file format and associated resources to ultimately enable an implementation of an open source image viewer for those files.
