Dear users,<br><br>In grads, we have many conversions like xy2w, xy2gr, w2xy, w2gr, gr2w, gr2xy, ll2xy, pp2xy.<br><br>What is the difference between these different co-ordinate systems like, world coordinates, grid coordinates, XY coordinates, LON/LAt coordinates and page coordinates ? <br>
<br>Can anyone having idea about these explain me?<br><br>thanks and regards,<br><br>Subhadeep<br>IITM, Pune, India.<br>
