EPSG:4326 - WGS 84

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, plus NAD83(CORS96) and NAD83(HARN), can be considered the same within the accuracy of the tfm. In USA only replaces tfm code 1900.
