NAD83(CSRS) / UTM zone 11N

Canada , accuracy 1.0 m, code 1946 (default) [7]
Canada , accuracy 2.0 m, code 1842 [3]

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Approximation derived from tfm code 6864 ignoring time-dependent parameters and assuming ITRF96(1997.0) and WGS 84 can be considered the same within the accuracy of the transformation.
