Convert FTS to CAL

The Flexible Image Transport System (FTS) file extension, is predominantly utilized for the storage, transmission, and manipulation of scientific and astronomical data. Developed by NASA in the late 1970s, this standardized format facilitates data interchange among the astronomical community. FTS is highly extensible, supporting various data types such as images, tables, and multidimensional arrays. Its widespread adoption stems from its capability to encapsulate metadata efficiently, enabling accurate and effective exchange of complex datasets among researchers and institutions.

The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
