I am familiar with PROJ4 but I don't see any such function in PROJ4. We do care about accuracy and therefore I am not willing to use simple methods that consider earth as perfect to compute such distance. <br>
<br></div>Please let me know if there is such functionality exists in PROJ4. <br><br>Thanks<br><br></div>
