<div>Hi all,<br clear="all"></div><div><br></div><div>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++.</div>
<div><br></div><div>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?</div><div><br></div><div>Thanks,<br></div><div><br></div><div>Evan Miller</div>
