NTv2 Update

NTv2 tool can now transform coordinates (geographic, UTM/MTM/Stereo) between the NAD27, ATS77, NAD83(Original), and NAD83(CSRS) reference systems using binary Grid Shift Files (.GSB format) where available. Users can now select different grids by clicking on the "select grid" link below.

Help for NTv2

The NTv2 National Transformation tool can transform coordinates (geographic, UTM/MTM/Stereo) between the NAD27, ATS77, NAD83(Original), and NAD83(CSRS) reference systems using binary Grid Shift Files (.GSB format) where available. 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.
