Alberta Survey Control Marker (ASCM) index maps are a graphical representation of the provincial spatial referencing system. The index maps display the location of integrated ASCMs in relation to various base mapping features including the Alberta Township System, hydrography, geo-administrative boundaries (Municipal and Canada lands), road networks, railways, and airports. In addition, index maps covering urban areas include street names, networks, and major facilities (schools, hospitals, etc.). Only those markers with a marker condition of GOOD or ANOMALOUS are displayed on the index maps. ASCM index maps are available from https://www.alberta.ca/geodetic-control-unit.aspx#toc-3.
