Continuous Acquisition and Life-cycle Support Type 1 Image (.cals)

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.

Pyramid Encoded TIFF (.ptif)

The PTIF (Pyramid Encoded TIFF) file format, developed by Image Magick, is a specialized variant of the TIFF image format designed to store multiple resolutions of the same image within a single file. This enables efficient zooming and panning in applications without losing image quality. PTIF files are commonly used in geospatial imaging, remote sensing, and medical imaging due to their ability to handle large, high-resolution images efficiently. The format was introduced to address the need for handling large image datasets more effectively in these fields.
