During the 1960’s to 1980’s, The City of Calgary surveyed cadastral ties (CADTIES) between thousands of Alberta Survey Control Markers (ASCM) and nearby legal survey monuments and other reference points. These Calgary ASCM CADTIES were surveyed under the supervision of an Alberta Land Surveyor and the information was recorded on sketches referenced to the old Alberta Survey Control (ASC) numbering system. ASCM tablet marking were usually the same as the ASC number. The Calgary ASCM CADTIES dataset includes 193 PDF files containing approximately 8000 sketches. The information has not been maintained or updated for many years.

The High Precision Network (HPN) is the primary survey control network necessary for development, surveying and mapping in Calgary and is a subset of the Alberta Survey Control Marker (ASCM) network.
