<body class='hmmessage'><div dir='ltr'>Hi Andrzej,<br><br>I use MapSource 6.16.3 and it doesn't show the great circle line<br>when I open the attached gpx file.<br>What did you did to create your picture?<br>Up to now I found only one tool which seems to show<br>the great circle: Google Earth<br><br>This is quite important. If Garmin software doesn't care <br>about the difference, we can remove more (or different)<br>points from the img file without visible effects.<br><br>Ciao,<br>Gerd<br><br><br><div>Date: Fri, 1 Aug 2014 13:45:18 +0200<br>From: popej@poczta.onet.pl<br>To: mkgmap-dev@lists.mkgmap.org.uk<br>Subject: Re: [mkgmap-dev] help needed<br><br><pre>Hi Gerd,<br> <br> > JOSM doesn't display the so called great circle<br> <br>It's a bit disappointing that QGIS and Global Mapper don't use great <br>circles either. Probably for faster redraw.<br> <br>Global Mapper can use great circle for distance tool. Drawing all lines <br>with this tool I can estimate distance to about 14km. Funny is that <br>great circle comes 14km above point D, while rhumb line is 29km below D. <br>Your reference was correct saying, that D is right of course.<br> <br>Mapsource draws direct routes as great circle, this can be used to <br>calculate distance too, see attached picture.<br> <br>-- <br>Best regards,<br>Andrzej<br> <br> <br></pre><br>_______________________________________________
