Hi all,

I need a method for the forward problem of geometric geodesy:  Given an initial point (lat1,lon1), find a second point(lat2,lon2) at a specified azimuth (degrees clockwise relative to the north) and distance (in KM)  along a line on a specified ELLIPSOID (WGS84)

any idea if the sharpMap library includes such a method, and if yes what is it's name/library?

 

thanks

It has not, but you can easily do it yourself. All the relevant math can be found here:
