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.

Description

In order to facilitate user needs working with coordinate data referenced to different reference frames, Geodetic Control has developed transformation grids to allow users to accurately transform 2-dimensional coordinate data from one reference frame to another. This fact sheet reviews the two primary transformation grids available, their format, and where to obtain them.

Description

Geodetic Control publishes coordinate data with respect the North American Datum of 1927 (NAD27) and the North American Datum of 1983 (NAD83). The NAD83 coordinate data is further broken down into coordinate data relative to the original implementation of NAD83 (NAD83(Original)) and the Canadian Spatial Referencing System implementation of NAD83 (NAD83(CSRS)). This fact sheet outlines the format and location where Alberta Survey Control Marker (ASCM) coordinate data is available.

Description

The National Transformation Analysis Data tables allows land surveyors, engineers and others to gain insight into the quality of transformation grids that allow them to transformation coordinate data from NAD27 to NAD83(Original) and vice-versa, NAD83(Original) to NAD83(CSRS) Epoch 2002 and vice-versa, and NAD83(Original) to NAD83(CSRS)v7 Epoch 2010 and vice versa.

Description

Alberta Survey Control Marker (ASCM) data is available for three reference frames: The North American Datum of 1927 (NAD27), the original derivation of the North American Datum of 1983 (NAD83(Original)), and the Canadian Spatial Reference System (CSRS) derivation of NAD83 (NAD83(CSRS)). This fact sheet reviews the NAD27 and NAD83(Original) datums including currency of coordinate data, coordinate differences between datums, and phasing out of ASCM integration and maintenance of coordinate data on each datum.
