Selected transformation

Name: CSRN2025.0 (NAD83 2011) to WGS 84 (1)

Method: Geocentric translations (geog2D domain)

Remarks: For many purposes CSRN2025.0 (NAD83 2011) can be considered to be coincident with WGS 84. This approximation ignores the ~2.2m offset of CSRN2025.0 (NAD83 2011) from the geocentre, the low accuracy of the WGS 84 ensemble and the application of tectonic plate motion to WGS 84 data.
