<div><div>Hi Helge,<br><br>sounds like a special case in the OSM data which was introduced in April (or end of March).<br>If you want to find out more, please check the log. Enable logging with a command like this:<br><br>java -ea -Dlog.config=logging.properties mkgmap.jar ...<br><br>See <a href="http://wiki.openstreetmap.org/wiki/Mkgmap/dev#Enabling_Debugging" target="_blank" title="http://wiki.openstreetmap.org/wiki/Mkgmap/dev#Enabling_Debugging">http://wiki.openstreetmap.org/wiki/Mkgmap/dev#Enabling_Debugging</a><br>for more details<br>If you use your own style files, please try what happens with the default style.<br>If you can find a clue, please post a link to the input file(s) for mkgmap<br>and the options / script that you use and describe the route that doesn't <br>work (start/end point, routing preferences (car,bicycle, shorter/faster etc).<br><br>Gerd<br><br><br><div><hr id="ecxmcntstopSpelling">From: helge@helge.net<br>Date: Mon, 13 Apr 2015 23:10:02 +0200<br>To: mkgmap-dev@lists.mkgmap.org.uk<br>Subject: [mkgmap-dev] Bug in created maps?<br><br>Hi<div><br></div><div>Over the last few days I have experienced a problem that I have not seen before. My Garmin GPS have severe issues routing me to/from my home. Basically the GPS makes big jumps from something that I can’t see as anyting on OSM before it merges with an existing road.</div><div><br></div><div>Have a look at these images: <a href="https://flic.kr/s/aHsk6DUitu" target="_blank" title="https://flic.kr/s/aHsk6DUitu">https://flic.kr/s/aHsk6DUitu</a><br><div>
