[ Update this Record ]

Summary
Abstract: The Primary Vertical Bench Marks, Canada, Level 1 (PVBMC1) 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). The data format of the PVBM1
information could be GML (ASCII) or SHAPE. PVBM1 information includes
geographic and UTM coordinates, orthometric elevation, marker information
description, and inspection data.The primary vertical bench marks are designed
to serve as a fundamental vertical reference frame for spatial positioning in
Canada (the geodetic Canadian Spatial Reference System - CSRS). Spatial Data
