NTv2
Sample Batch Files Available
If you need help with the “Batch Processing” file format for CSV files you can now download sample files by clicking on the "Help for NTv2" link below.
Grid shift files download
Grid shift files are now available for download on the coordinate transformations page.
New Lambert conformal conic projection available
The NTv2 tool transforms coordinates (geographic, UTM/MTM/Stereographic/Lambert conformal conic) between the NAD27, ATS77, NAD83(Original), and NAD83(CSRS) reference systems using binary Grid Shift Files (.GSB format) where available. Users can 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/Stereographic/Lambert conformal conic) 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/Stereographic/Lambert conformal conic. All coordinate fields are required in the chosen coordinate system.
