EPSG:17725 DEPRECATED

Alberta 3-degree TM reference meridian 120 W

Attributes

Data source: EPSG

Information source: Alberta SRD Lands Branch, Geodetic Fact Sheet 10. http://www.srd.gov.ab.ca/lands

Revision date: 2008-01-11

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 deg W; however use of UTM encouraged in these areas.

Method: Transverse Mercator

Area of use: Canada - Alberta - west of 118°30' W.
