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.
