NAD83(2011) / Oregon Coast zone (m)

Available transformations
to EPSG:4326
No other targets exist for this CRS

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.
