Scope: Cadastre, survey control and engineering survey in urban areas, typically in all municipalities that previously comprised the 73 Municipal Integrated Surveying and Mapping (MISAM) areas, also known as urban cadastral map areas. For rural areas use UTM.
Remarks: If used for rural area control markers, area of use is amended to west of 118°W; however use of NAD27 / UTM zone 11N (CRS code 26711) encouraged in these rural areas.
Area of use: Canada - Alberta - west of 118°30' W.
Coordinate system: Cartesian 2D CS. Axes: easting, northing (E,N). Orientations: east, north. UoM: m.
