Geodesy, engineering survey, topographic mapping.
Replaces CGVD28 height (CRS code 5713). CGVD2013(CGG2013) height is realized by geoid model CGG2013 (CT code 9246). Replaced by CGVD2013a(1997 / 2002 / 2010) height. CGG2013a is identical to CGG2013 except in the western sector of Lake of the Woods.
