<div dir="ltr"><div><div><div>Tobias,<br><br></div>Thank you for that suggestion. I am now using the geographiclib routines in Shape Tools' XY to Line routine that was released today. I am still including Great Circle as an option and if you zoom in you can see the differences.<br><br><a href="http://plugins.qgis.org/plugins/shapetools/">http://plugins.qgis.org/plugins/shapetools/</a><br><br></div>All the best,<br><br></div>Calvin<br><div><div><div><div><div class="gmail_extra"><div class="gmail_quote"><span class="gmail-"></span><br><span class="gmail-"></span><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><span class="gmail-">
</span>Wait, it's way better to use this one:<br>

<br>
There's a Python port and it's extreme accurate and quick.<br>
It's under MIT and it works great (just tested it).<br>
<br>
It also works with WGS84 and all other ellipsoids (WGS84 should be<br>
fine for most of the users).<br>
<br>
This might be the easiest and best way for accurate distances and<br>
azimuths.<br>
