NAD83(2011) / RMTCRS Fort Peck Sioux (ft)

Puerto Rico , accuracy 2.0 m, code 9774 (default) [3]

Selected transformation

Method: Geocentric translations (geog2D domain)

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