Caption title. "The Pacific Weather Centre uses Unifax recorders to produce hard copies of satellite images reconstructed from analog data transmitted through facsimile lines. Previously quality control has been a haphazard affair based on subjective assessment. This has resulted in some problems since image appearance can vary for a number of reasons. ... The densitometer is a graphic arts instrument which can measure the density of print on a flat surface. It can be used to obtain high resolutin reflected light measurements from the printed images." gccst Weather forecasts gccst Satellite imagery Canada. Environment Canada. Canada.
