The information contained in this product is established under the CD datum. The CHS does not establish and maintain other vertical datums such as CGVD28, CGVD2013, IGLD (1955) and IGLD (1985). References to these datums represent the best available information, to be used with caution and sound judgment where required, but it is not intended to be used for navigation.
