NAD27 / Alberta 3TM ref merid 120 W

Available transformations
to EPSG:4326

Selected transformation

Grid Files: conus.las conus.los sdhpgn.las sdhpgn.los

Remarks: Transformation steps are from NAD27 to NAD83(HARN) (22) (code 6739) assuming that NAD83(HARN) is equivalent to WGS 84 within the accuracy of the transformation.

Attributes

Unit: metre

Geodetic CRS: NAD27

Datum: North American Datum 1927

Ellipsoid: Clarke 1866

Prime meridian: Greenwich

Data source: EPSG

Revision date: 2008-06-24

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.
