EPSG:3969

NAD83(HARN) / Virginia Lambert

Selected transformation

United States (USA)

code 1900

Accuracy 1.0 m
7 parameters

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Approximation derived ignoring time-dependent parameters and assuming ITRF94(1996.0) and WGS 84, plus NAD83(CORS94) and NAD83(HARN), can be considered the same within the accuracy of the transformation. Replaced by NAD83(HARN) to WGS 84 (3) (code 1901).
