Download or read book Experimental Large-scale Snow and Ice Mapping with Composite Minimum Brightness Charts written by E. P. McClain and published by . This book was released on 1969 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Composite Minimum Brightness (CMB) chart is a computer product derived from digitized and rectified satellite video data. The minimum brightness values mapped over an area during a given period are composited and displayed as a means of suppressing transient cloudiness and enhancing major snow and ice features in the satellite imagery. Examples are presented, and limitations and verification of the technique are discussed.
