Caption title. Includes bibliographical reference (page 2). "The Pacific Weather Centre utilizes Unifax II facsimile machines to reproduce satellite imagery. In order to maintain quality control over the images produced, consideration must be given to adjustable components within the machine that may have an effect on image quality. Since a number of Unifax II machines are in use at PWC, it is necessary to calibrate all machiens to operate and produce image results with no variations of image, quallity, and contrast." gccst Technology gccst Weather gccst Satellite imagery Canada.
