Résumé(disponible en anglais seulement)
This Windows application converts geographic coordinates between any pair of ten systems; latitude and longitude as well as different grid and map projection systems. The grid systems supported are Township and Range, British Columbia's NTS-based grid system, the Canada Lands system, the UTM system, and the UTM-based Military system. The projections supported are Mercator, Lambert, Polyconic, and Albers. Transformations can be done in either the NAD27 or NAD83 datums. Transformations between NAD27 and NAD83 require the grid shift files included with the NTV2 software (see above). The appropriate grid shift file, usually NTV2 0.GSB must be renamed GRID.GSB and placed in a fixed directory:

e.g. MathTool.exe, MathTool.ini, readtool.txt ==> \MathTool
GRID.GSB, NTV21.exe ==> \NTV2
INFILE.TXT, OUTFILE.TXT (temporary files) ==> \NTV2

Note that the Twp Rge grids are assumed to be the same in each datum with the NAD83 coordinates being obtained by application of NTV2 on the NAD27 coordinates. To use the tool the user (1)enters a location and defines its coordinates system on the input source screen, (2)defines the desired output system on the output destination screen, and (3)selects the find button. The application then calculates the location in the new destination system. The application is a Delphi (Trade Mark) run-time module for Windows XP and 95/98/00.

Note that NTV21.exe, derived from the NTV2 software (see above), can also be used in batch mode by setting INFILE.TXT to a file with records giving NAD (27 or 83), latitude, and longitude.
