Consider the source code for GeoTrans, the package available from www.nga.mil - however, I don't know if it's C or C++.

Subject: [Proj] geod C library?

Hi all,

I am looking for the functionality provided by "geod" and "invgeod" (great circle calculations) wrapped up in a plain C library. I found Charles Karney's Geographic Library, but that's C++.

Does anyone know of such a library? Is there any reason (other than time and effort) that Proj.4 doesn't provide a geod API?
