Transform Coordinates
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.
Frequently Asked Questions
How do I convert NAD83(2011) to WGS 84 coordinates?
Use the coordinate transformation tool above to convert NAD83(2011) (EPSG:6318) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 2m accuracy.
How do I transform NAD83(2011) to WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:6318 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the NAD83(2011) to WGS 84 transformation?
This transformation (EPSG:9774) has an accuracy of 2m using the Geocentric translations (geog2D domain) method. Area of use: USA - CONUS and Alaska; PRVI.
