NTv2

Help for NTv2

The NTv2 National Transformation tool can transform coordinates (geographic, UTM/MTM/Stereo) between the NAD27 and NAD83 reference systems using a binary Grid Shift File (.GSB format). The transformation is 2D (horizontal) therefore heights are not required.

Two coordinate systems are available: geographic and UTM/MTM/Stereo. All coordinate fields are required in the chosen coordinate system.
