Gridconv - datum and national grid projection calculations
GridConv is a small software package for doing various datum and national grid projection calculations.
From the GridConv README :-
- Convert between Latitude, Longitude, Altitude and Eastings, Northings, Altitude of a Transverse Mercator projection
- Calculate the Great Circle distance and direction between two points
- Do the reverse of the above - calculate the location that you would end up at if you travelled a specified Great Circle route
- Do conversions between ECEF (Earth Centred Earth Fixed) and Latitude, Longitude, Altitude
- Convert between datums whose axes are parallel
