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.
