When trying to implement new feature we have figured out in literature, that declination against grid north is called "needle deflection". Is this english term, OK? It means, instead of declination, you would specify<div>
<br></div><div>needle-deflection 10 deg</div><div><div><div><br></div><div>In Slovakia, we call it "magnetic deflection". Or may be just</div><div><br></div><div>declination-north grid</div><div><br></div><div>
would be sufficient. Any comments?</div><div><br></div><div>S.<br><div><br></div><div><br><br><div class="gmail_quote">On 14 October 2012 15:01, Ben Cooper <span dir="ltr"><<a href="mailto:ben@caver.plus.com" target="_blank">ben@caver.plus.com</a>></span> wrote:<br>
