Primary Vertical Bench Marks

Description

The Primary Vertical Bench Marks are (approximately 80000) monuments established about every 2 km along major highways and railways across Canada. Elevations issued by the Geodetic Survey Division (GSD) are those based on the 1928 adjustment of the national levelling networks - Canadian Geodetic Vertical Datum 1928 (CGVD28).
