AB_CSRS.DAC
Parameter file is from NAD83 to NAD83(CSRS)v4 (3) (code 9244) assuming that NAD83(CSRS)v4 is equivalent to WGS 84 within the accuracy of the transformation. This file AB_CSRS.DAC will need to be renamed to AB_CSRS.gsb to run in some software.

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.
If used for rural area control markers, area of use is amended to between 116°W and 112°W; however use of NAD83 / UTM zones 11N and 12N (CRS codes 26911 and 26912) is encouraged in these rural areas.
Canada - Alberta - between 115°30'W and 112°30'W.
