C++ Question

how do I get a new coordinate in geodetic (Lat/Lon) from a reference point (which is in geodetic) after some translation (in meters) on earth surface, and also I need to do the calculation using true earth ellipsoid model such as WGS84.

for example:

- suppose I have reference point of 10.32E, -4.31N
- then I do translation of (3000,-2000) meters ( which is move the point 3000 meters to east and 2000 meters to south
**on earth surface**. - then I need the coordinate of new point
**in geodetic**.

thank you
