EPSG:6622

NAD83(CSRS) / Quebec Lambert

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

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 can be considered the same within the accuracy of the transformation.
