NAD83(CSRS)v7_E2010_CGVD2013_Provincial_Data - March 2021.pdf

Description

This document describes the contents of an excel format spreadsheet for 32,971 published ASCMs. The coordinate and elevation information for these ASCMs are based on the NAD83V7.0.0.AB.1 provincial readjustment of the Alberta Survey Control network. As a result, the geographic coordinate data is referenced to the North American Datum of 1983 Canadian Spatial Reference System version 7 geometric reference frame at Epoch 2010 (i.e., NAD83(CSRS)v7 E2010). The elevation data is referenced to the Canadian Geodetic Vertical Datum of 2013 (CGVD2013). This spreadsheet is current to November 6, 2020.
